Dear Ralph:
I have a good one for you. I own a 2002 Yamaha SXViper. It originally came with electric start, but since the sled was sort of heavy compared to the SX700 I was used to riding, I decided to remove the (weight) of the battery and electric start. I did leave the ring gear on the primary clutch though, as this should smooth out some of the crank vibrations (I read that in SnowTech).

Any way, now that I’ve done this I’m getting some weird electrical problems. For instance, the tachometer goes wacko on me and my hand warmers don’t seem to work as well.

I was very careful when removing the battery and start motor to make sure all connectors were well insulated, so this doesn’t make any sense. Did I cause this to occur, or is it simply a coincidence these things started at the same time?

I almost hate to tell you that you caused it. According to Yamaha, the 2002 SXViper ER models need to have a charged battery to operate properly. The electrical system on this particular model does not have the same smoothing capacitors as the non-ER models. As a result, operating the sled without a battery installed will cause a host of strange electrical problems; like you are experiencing.
