Voltage meters for my PC800

Since I was already installing heated riding gear and because of all of the stories of faulty rectifiers and dead electrical systems, I decided to install an analog voltage meter.  I chose the Honda Marine voltmeter [Note: links to this keep changing so your best bet is to go google “Honda Marine Voltmeter” and you should find one for sale]. The gauge is waterproof and lighted.  Rather than buy it from some random website, I decided to get it from my local marine supply store.  Next time I’ll buy it online.  The local store took forever to get it and then charged me double what it would have cost online.  They even charged me for shipping!

While I was at it I decided to get an idiot light because I suspect that if I didn’t have it, I’d end up being an idiot someday.  I ordered a Signal Dynamics Heads Up Voltage Monitor. After going on several rides with it installed, I can say that I am VERY glad that I chose to install both an analog gauge AND an idiot light.

To make the hole for the analog gauge I found an appropriate sized hole saw at the local home improvement store. The small hole for the LED for the idiot light only took a little drill that I had in my tool chest.

I ran wires for the gauges back along the right top frame tube to the auxiliary fuse block I installed in the trunk. Most people hook a voltage gauge directly to the battery. I chose to connect mine to the fuse block instead. Sure, I might lose 0.05 volts going through some extra connections but I think it’s better to be cautious with my bike’s voltage anyway. I don’t need to squeeze every last tenth of a volt out of the system. At least not yet anyway…

My setup. The idiot light LED is in the upper left corner of the speaker blank. It ends up being in the extreme bottom portion of my peripheral vision when my head is up while riding. So far it hasn’t been distracting at all although I haven’t ridden during any dark nights yet. There are plenty of photos of other people’s setups on IPCRC. This is just the way I did it because I liked it this way. I’d be interested to see what other people come up with for their installations in the future 🙂

Cigarette lighter socket installation on the PC800

During the bike overhaul last month I decided to install a cigarette lighter socket on my PC800.  The most logical place to me to install it was in the “glove box” compartment on the left side of the dash.  While buying some antifreeze at the local auto parts store I found the cheapest aftermarket cigarette socket they had and bought it.

Installation was pretty easy.  I found a drill bit that was the right size and popped a hole in the front side of the “glove box.”  The cigarette lighter socket slid right into place and screwed down tight.  I then proceeded to go overboard with the black silicone RTV, covering the ENTIRE length of the outside of the socket with the stuff.  Better safe than a shorted out socket, right?  Right?!?

I ran the wires for the socket around the front of the instrument panel and down the top frame tube on the right side.  I chose to go on that side of the bike because I had another set of wires installed over there for a voltage meter in the dash and figured I might as well put both sets of wires in the same set of zip ties.  Previously I had installed an auxiliary fuse block in the trunk which I wired the cigarette lighter socket into.  I made sure to put a 15 amp fuse (and make everything from there to the socket rated for 15 amps) so that when I get an electrical compressor, I can use the cigarette lighter socket up front.  Most of the ones I’ve seen for sale online require a 15 amp fuse.

Unfortunately I was so excited to install the socket that I didn’t take any photos of the installation process.  Instead, here is a photo of it all done.  The socket and the plug cap are at the top end of the “glove box.”  The screwdriver is so I can pop of my radiator cap to make sure I have enough fluid (replaced the coolant recently).  The two knobs at the bottom at the photo are part of my Heat Troller installation.  It looks like there should be plenty of space in there to charge a cell phone or Ipod while riding.  Wouldn’t recommend doing that in the rain though 😉

Heat Troller installation on my PC800

After some super cold (for western Oregon) weather last month where it hit 8 F at night, I decided it was time to get a few pieces of heated riding gear.  Enter Warm n Safe’s Heat Troller.  Doing some research on the several companies that carry digital riding gear thermostats, I decided to get it from Warm n Safe.  People over at ADVRider really like them and everyone who has used them seems to think they’re a good company.

The installation process went fairly smoothly.  I chose to put the dual controllers and indicator lights in the left dash plastic just above knee level and below the “glove box.”  The template that comes on the instructions for the Heat Troller worked just fine to help me align and drill the holes.  I ended up using the brass spacers that are included in every permanent mount Heat Troller.  There’s a good chance I could have gotten away without using them but by the time I realized that, I had already made the holes too big to turn back.  In the end it worked after adding a washer to each thermostat.  I used it to fill up some extra space.  Oops 🙂

While I was putting one of the thermostat controls into its final position I managed to snap off one of the legs on the indicator LED.  A quick trip to my soldering iron and it was all fixed up.  Those little LED legs are fragile!  And also too long for the way I installed it.  I bent mine in kind of a U shape to make the LEDs be at the proper height.

To button up the thermostat installation, I covered both thermostat circuit boards in dielectric grease.  The hope is that by covering them in dielectric grease, I will never have to worry about water or road grime shorting out the Heat Troller.  If you don’t want to use grease, I remember reading (I think) on the Warm n Safe website that clear nail polish works well, too.

And now for a small rant:

I don’t understand why the Heat Troller or any of its competitors doesn’t come with a way to disconnect the thermostat controls from the loooong cables that run back to the Heat Troller control unit.  My installation is such that I will have to take the whole Heat Troller off the bike if I need to take off the dash plastic in the future.  It makes sense to me to add in a couple of connectors near the thermostats.  That way, it would be a snap to disconnect whatever plastic panel the Heat Troller thermostats happen to be connected to.  I’d even pay an extra $10-20 for this feature!

Back to the story…

I found the best place on the bike to mount the Heat Troller control unit box thing is underneath the seat on the left side of the bike.  I used the double-sided sticky tape Velcro stuff right on the gas tank where the big curve in the tank is (at the back by the trunk).  That space is just a big void otherwise.  Might as well fill it with something useful!  This also provides enough length to get the power cable to the battery (or in my case, an auxiliary fuse block in the trunk).

The cables running to the front of the bike were routed up the top left frame tube and zip tied down.  After a couple of rides I pulled the plastic panel off the bike along that frame rail to check to see how everything is doing.  No melting so far!  I guess the real test will come in the summer but judging by the other wires that run along that same path, I shouldn’t have a problem.

Initially I was planning to have the two coaxial plugs that hook to heated clothing from the Heat Troller stick out from under the seat.  I ended up opting to install some BMW plugs on the dash plastic instead.  The reason I did this is for all those days during the year when I don’t need heated riding gear.  On those days I’d much rather have some nice clean socket plug caps than a couple of dangling pigtails sticking out from under the seat or between the body plastics.  Warm n Safe has a nice set of BMW plug sockets and a good set of BMW plug connectors with an 18 inch cable and coaxial plug at the end.  At the same time I also picked up some 12 or 18 inch (I forget now.  Measure it yourself to make sure you’re getting the right one!) coaxial plug cables to extend the reach of the cables up to the BMW plug sockets.

WARNING FOR TALL RIDERS:

In retrospect I wish I had installed the BMW socket plugs up higher on the bike.  The place I ended up putting them (see photos below) is right where my knee goes when I ride.  It isn’t a HUGE annoyance but it is a bit annoying.  I am planning to buy some right angle BMW plugs in the near future to replace my straight-out BMW plugs.  However had I measured 5 times instead of 4 before cutting, I would have put them up higher on the plastic where my knee won’t hit.  If you’re a shorter rider this probably won’t be a problem but if you’re tall, double-check the fitment before you cut plastic.

After I tightened down the BMW sockets, I coated the sockets from top to bottom with silicone RTV sealant stuff.  I chose to use black in case any was visible from outside the plastics.  Now those plugs are water-tight and won’t short out as easily.

Having ridden it for about five hours in cold weather since installing the Heat Troller I can say that I absolutely love having heated gear.  The position of the controller knobs is perfect to reach while riding.  The little LED lights are out of my line of sight when my head is up but it only takes a quick glance down to see the status of the units.  Aside from the minor plug inconvenience, I would say that this installation is a success.  In the future though I think I will add a toggle switch on the dash to quickly kill the power to the Heat Troller.  This will be very useful when I am running my heated gear at full blast and need to stop at a stop sign or stoplight.  No more dangerous voltage drops!

Here are a few photos of the finished installation. I got too excited cutting plastic during the install to remember to take photos of the process.

The controllers and BWM sockets are on the left side mostly obscured by the handle bars.

If I ever install another Heat Troller on another motorcycle, I will be sure to verify that my knee won’t hit the plugs.
