Sort of.If the batteries really had a lower voltage then the tractor would need to draw more amps to produce the same amount of power. Amps are what heat cables, so the less amps (higher voltage) the better.
Now the Amp meter is simply a sensitive volt meter reading voltage across a shunt, in this case a specific length of wire from the batteries to the tractor. The more current you pull the more resistance there is and thus the higher the voltage drop is over that length of cable.
If the cable's ends are not terminated properly or are dirty the amp meter will read high (and the cables will get warm). Likewise if someone changed the length of cable the amp meter will read low (less voltage drop).
I think the problem is the cable connectors are dirty/corroded/loose. C On 10/16/2021 2:40 PM, Paul Anderegg wrote:
I have an E12M I am troubleshooting. The batteries were completely dead upon arrival but they somewhat came back to life. The voltage gauge always reads low but the machine can still mow for over an hour. The amp gauge often reads high from the upper green to all the way pegged by driving in any gear. If I turn the mower deck on it's always 100% pegged an amp gauge. Does anyone know if this is normal when the batteries are compromised? Or could there be a short somewhere? -------------- next part -------------- An HTML attachment was scrubbed...
