The Goat amazes me again and again

[mutt_r]

Today I wanted to wash and prepare the Goat for an event we have here next weekend. 1st start the Goat. Nothing happened. No instruments, no starter, absolutely nothing.

So I took my M151 and the jump start cable. The goat starts immediately. But the instruments still don't work, the light, turn signal and so on doesn't work. Unusual. Batteries measured with the multimeter, both OK.

Where should I start with my search to solve this issue? Has any of you ever had this problem?

Appreciating any clues. Thank you in advance and best regards

The 3-53 does not need electricity to run. I suspect there is corrosion between a battery cable and either a battery terminal or where the cable is attached to the chassis.

I'll check the cables between the batteries and the chassis.

Cables between batteries and chassis are good.

Checked on the terminal strip today. All lugs have 25V (only lug #1 has 0V where cable #15 is connected). When turning the master switch ON, the voltage goes down to 1.25V on all lugs.

Where to start now?

When you start the goat with the cable to your M151, leave the cable connected. With the cable still connected, are your instruments, lights, etc functional? If so, I would suspect your batteries or a damaged cable. Just because you can measure the correct voltage with the multimeter, doesn't mean that one of your batteries isn't going open internally under load. With the cable still connected, if your lights and instruments are still dead, you must have a problem with an electrical connection. To make certain that each of your cables are good, you can take a jumper cable and parallel each cable connection on the goat. Sometimes a cable can fail internally and show no sign of damage. Good luck.

When I turn on the lights of the M561 while the jump cable is still connected to the M151, the instruments, lights and flasher are also not working. Will spend some time on looking for a damaged cable. Had a similar problem with the connection between tractor and carrier a few years ago. Finally a cable inside the connector was broken.

Many thanks for all your hints. Found the problem and the solution today. The bolt for grounding the battery cable on the passenger side was junk. Drilled a new hole, took a new bolt and washers. And finally the Goat started like yesterday. While there was a metric bolt used by a previous owner, it looked like a previous problem as well.

You get the goat info I sent?
