Ammeter Indicating +10amps

Recommended Posts

Ran d

I have a 1969 Electro 12 and recently my ammeter was showing +10amps at near full throttle. Battery voltage with tractor off measured 12.7 vdc. Battery voltage with tractor at near full throttle measured 13.9 vdc. I have a couple concerns, (1) If I run the tractor for several hours with the 10 amp overcharge, will Battery voltage increase and possibly damage the battery? , (2) I am at a loss as to why the ammeter is reading 10 amps. I have 3 kohler pn 41-403-06 voltage regulator/rectifiers and all give me the same result of 10 amps overcharging. I checked continuity on the stator wires to ground and both showed no stator short to ground. Welcome any suggestions?

Load Test the battery. Weak batteries cause issues.  also use your Multimeter  or replace the ammeter to confirm the 10 amp reading...

Load test was acceptable.

My C100 shows over 10amps after cold start then settles around 3amps, battery sits at 14.9vdc @ 3600.

You may have a connection that is corroded or needs to be tightened. A poor connection will act like a resistor and draw current from the charging system, Clean and tighten ALL electrical connections including grounds.
