CONTROL CIRCUIT BOARD
DIAGRAM 20 & 50 AMP
The control circuit board contains 5 light emitting diodes
(LED’s) to help pinpoint problems. When the LED’s
light, it is an indication that power is being supplied to
the function listed below the circuit board diagram (e.g.
when LED designation D17 lights, incoming power to
the circuit board is supplied) . If a given function is
obviously not working, but the related LED is lit, check
the other components within that function (see
TROUBLESHOOTING).
