This is my 2nd attempt to post this info, something did not work the first time. . . My 2000 Mobius V started right away this spring, but letting it warm up I noticed after about 5 min the voltage gauge was reading 13.8 volts, then suddenly dropped to about 10-11 volts and then the engine quit. I had to reset the main 20 A breaker on the integrated circuit board, wait about 2 minutes and it started right back up, but then would trip the breaker again. The longer I waited would allow it to run longer.
I disconnected everything but the gauges and wiring harness from the main circuit panel and even switched to my truck battery to be safe, but it would still stop running at random times. It did appear to be better, so I took it to the lake, and it stopped after 2 min. Frustrated, I bypassed the 20 A fuse and it started right up, and I then proceeded to idle on the trailer and occasionally rev it to 3-5 k and it ran like a champ for about 3 min. It then died and I have been unable to start it even after a day of rest. It might have been in my head, but the wires on the circuit board appeared warm to the touch.
At this point, I've verified I'm getting spark on several cylinders. I pulled the distributor cap and noticed a fair amount of corrosion on the terminals, yet it's creating spark. I can smell fuel, yet the plugs did not seem overly wet. Another odd bit is two of the 8 plugs were quite black, but the other 6 were very clean, since they are new MR43LTS plugs.
I'm concerned this could some wire that is shorting, but I'm not sure how to go about finding this. I think the hint is that the volt gauge showed a drop right before it died. I was watching the battery with a meter and noticed it also took a drop but still stayed around 12.3.
Any help or more troubleshooting steps would be very appreciated. I hate electrical problems.
