2.
Place pos. meter probe A on top
solenoid post. Place neg. meter probe
B on -48V battery terminal. Voltage
should be the same as the battery set.
If not, replace battery to solenoid wire.
3.
Turn key switch to the on position. The
solenoid should click. Place pos. meter
probe A on bottom solenoid post. Place
neg. meter probe B on -48V battery
terminal. Voltage should be the same as
the battery set and the top solenoid post. If
voltage is
less than 1
V different between large
posts, replace the solenoid.

controller has disconnected solenoid.
If voltage is good go to step 4.

Caused by: Battery pack voltage is over 67 volts. Field faults come from
excessive regenerative energy not being controlled by the resistor circuit.
1.
Verify battery pack voltage at the
time of fault. Voltage should be <63V.
Also verify charger output is not over
67.2V
4.
Place pos. meter probe A on
controller terminal B+. Place neg.
meter probe B on controller B-.
Voltage should be the same as the
battery set. If not, replace -48V battery
wire to B-. If voltage is still not the
same verify steps 2 – 4.
