Hello everyone,
I’m trying to diagnose some odd problems I’m experiencing with my EV and was
just running the motor off of an optima that I had laying around and was
wondering what the typical current draw of an FB4001 motor is off of 12 volts.
I’m seeing around 50 amps. It is mostly unloaded, it is still attached to the
transmission in neutral so it is spinning the gears.
My motor has sounded a bit whinier than I remember it since I got my car back
on the road (it was off the road for 9 years so my memory of the sound is a bit
dim).
I’m wondering if my bearings are in need of replacing.
Anyway, the problems I’m experiencing aren’t related to the bearings, it’s that
the Zilla is giving me error code 1131(short/load at precharge). I just pulled
all of the batteries and the controller out of the motor bay so I could take a
look at the motor. I haven’t been able to get a clear look at the brush
rigging yet but I didn’t see any sparks shooting out of the end of the motor…
that must be good right?
-Jeremy
