Pumps #’s 2142, 2390, 2532, 3126, 3170:
Battery Lead (+12volts):
Attach a
# 4 gauge wire
between the positive (+12V) terminal on the
battery and the large post on the solenoid opposite the black motor wire on the solenoid. If circuit
protection is required, Install an 80 amp (minimum) circuit breaker.
