Voltage issue for seat connection

Post by montanamax »

I’m the new owner of a 2007 R1200RT. I discovered the cable connecting to the seat had its plug missing. I’ve ordered a replacement but I discovered something which doesn’t seem right. I measured the voltage on the broken cable and found that with the ignition off, I got a measurement of 0.02V. With the ignition on but the heat control off, I measured 0.17V; in the ½ power setting, ~6V; in full ~12V. This can’t be that’s there’s even a minuscule current when the ignition is off, right? So what do you think is going on?

Does the motorcycle have both front and rear heated seats, if so, what are the voltages when compared with each other.

It's more than likely normal.

It has a canbus system which runs off low voltage and it's probably putting a low voltage to it for diagnostic purposes

I was hoping that the canbus system might be behind this observation in which case, I won't worry about it other than keeping the bike on a maintainer over the winter.

I had not looked at the rear seat but now I am curious to see what its voltages read.
