TESTING COMPONENTS
The following information applies to all charger types, unless otherwise noted.
TRANSFORMER
Please follow these steps before testing the Transformer:
Disconnect the battery.
Remove the charger cover.
Connect the charger to AC power.
First Transformer Test
You will be testing the transformer’s windings (with a good quality meter) to check the transformer’s voltages.
Your measurements should be within 10% of what is listed on the nameplate.
Second Transformer Test (120V Test)
Be sure to disconnect the transformer from SCR/Diode Block, PC board, and control transformer primary. You will need
to have the transformer isolated for this test.
1) Use a line cord with a 3 to 5 amp slow-blow fuse in an in-line fuse holder.
2) Power each section separately. Power from TB #1 and #6, and jumper leads 3 and 4.
3) If a fuse has opened, there might be a winding problem in the transformer. Perform all other tests in this
section before replacing the transformer.
