Manitou electrical woes

I have a 526 mlt, the battery runs down overnight if I don't disconnect it, the offside headlight is very dim. I've swopped it to the other side to test and it's fine, I presume I have a bad connection somewhere, is there a common place for it to go on these models, or how do I test for it with a multimeter?

I had this issue on a 627 and it was a faulty rev counter and hour clock. We only traced it when we heard it buzzing after the ignition was turned off. Disconnected it and the battery ceased draining overnight. Eventually got round to replacing it and never had the problem again.

Not saying this is your problem but you have a electrical drain somewhere and this was the cure in my instance.

Fairly sure there should be no power supply to the rev counter/hr clock with ignition off.:confused:

Disconnect the alternator, that can drain the battery over night. and try pulling fuses out one at a time.

Might find the radio drawing a bit too.

Or you maybe reading way too much in to it and the starter is junk which is all too common.

Dim headlight, might be a bad earth, so give it a new one just to test using a jump lead. Connect one end to the negative on the battery (or clean steel bodywork). Connect the other end to the common wire going to all the bulbs in the cluster including indicator (is it dim?).

Alternator test when stopped:
If you fancy connecting the Voltmeter (on DC 20Volts range) in the gap created when you disconnect the large output wire on the alternator, you shouldn't get more than a few stray volts on the meter. If you get full battery voltage its the alternator.
