CAUTION
l
Be sure to disconnect the battery plug before
measuring.
l
If using a megger, do not touch the measuring
terminals.
1. Remove all diodes from the transformer.
2. Use a megger to measure the following locations and
check the insulation.
l
Between the primary and secondary coils.
l
Between the primary coil and the steel core of the coil.
l
Between the secondary coil and the steel core of the coil.
1. Set the tester to the resistance (
) x 1 range.
2. Apply the positive (+) and negative (-) proves to
Anode(A) and Cathode(K) (or vice versa) to check the
resistance.
1. Measure the resistance to check the diode.
1. Check for damage or dirt.
If there is dirty or dusty, clean it away with compressed air.
2. Measure the insulation resistance.
