When I put my voltmeter on the battery (engine off) it's 6.3 volts or so. When I do it with the engine running, it jumps between 8 and 12, is this normal ???
That sounds high to me, Id expect it to rise from 6.5 to 7 and some over volts but NOT 12
Also, when I put the charger (ac charger) on the battery, the meter showed it was taking 9 amps, which makes me believe that the gauge should show at least a couple of amps, am I wrong in thinking this ?
If the ammeter is working and wired correct (sure it is???) if the battery voltage is rising to 7 volts and more YES the ammeter should show at least some charging amps. Do as my friend Bob M suggests and pass a magnet over its face and it should swing left n right if its NOT mechanically stuck. If its wired right theres only one wire on its hot supply side, thats the one that wires to the battery often via a wire to the big batetry cable on the starter switch or solenoid. Over on its other Load side the wire that runs to BAT on a cutout relay or Voltage regulator should be there plus a wire to feed lights and ignition etc. If the gens output is wired to the wrong ammeter terminal its charging amps dont get registered INSURE THE METER SWINGS USING A MAGNET THEN BE SURE ITS WIRED CORRECT
What are the chances of the gauge not working in the pos. direction?
Fair chance which a magnet might show or perhaps its wired worng as noted above
I read that if you are showing more voltage on the battery when the tractor is running, it's gotta be charging, is that correct?

Today's Featured Article - Upgrading an Oliver Super 55 Electrical System - by Dennis Hawkins. My old Oliver Super 55 has been just sitting and rusting for several years now. I really hate to see a good tractor being treated that way, but not being able to start it without a 30 minute point filing ritual every time contributed to its demise. If it would just start when I turn the key, then I would use it more often. In addition to a bad case of old age, most of the tractor's original electrical system was simply too unreliable to keep. The main focus of this page is to show how I upgr
