105 ammeter - Page 2

When load is applied (like headlights) and engine not running, the ammeter should show discharge. Either battery is hooked up backwards or wires are reversed on ammeter.

It is wired like it was befor the problem, and it looks like the old meter was ok since the symptoms havn’t changed. It starts and runs well, but judging by the time battery takes to bring the battery up to full charge, it’s not charging. Bet a nickel I’m missing something simple.

It seems the tractor is running at a constant loss.what is going on ? And now it’s snowing—perfect

You gotta go to the wiring diagrams...

I’ll Look at it again in the morning.

Make sure negative post of battery is going to frame. Easy to put these little batteries in backwards. They will start and run but not show charge. They show discharge but is is actually charging, it's just that the current flow is backwards. I just bought a 149 doing the same thing. Battery was backwards.

Meter only indicates charging, and only when the lights are turned on. Otherwise needle doesn’t move off zero. Heading out for another look at wireing connections soon.

The tractor is NOT wired correctly. See the previous post with the Wiring Diagram, download it, and make sure your tractor matches the diagram.

Wiring matches the diagram exactly. The tractor’s electrics were fine before the “split”, and the connections that were undone, went back where they were. I previously matched all connections with colored paint pens. I’m wondering if the VR is the problem,even though it tested as OK. Repolarizing is not supposed to be necessary with S/G’s, is it ? Any harm in trying to repolarize ?

The V/R will have NOTHING to do, with turning on the lights, and the Amp Gauge shows positive. Something is wrong here, I venture to say the Amp Meter is wired backwards.

Nope..Not at all.

Meter needle is at 0 all the time, it only moves and shows charge when the lights are turned on with the key in any position ( off, on, or start ). I’m going out to look at the wiring again, and hope to find it’s something stupid.
