SNUBBER ASSEMBLY
Please follow these steps before testing the snubber assembly:
Disconnect the battery
Disconnect the AC power.
The snubber assembly consists of a series resistor and a capacitor.
Before taking measurements on the Snubber assembly
1) Verify that the mounting wire is sound-properly screwed on and not broken.
2) Verify that the Snubber assembly is not burned, broken, or smoking.
To test the Snubber assembly
1) Disconnect a mounting wire and check for no continuity.
2) Replace if your meter reads less than 200K ohms.
REPLACING COMPONENTS
CAUTION:
THERE ARE DANGEROUS VOLTAGES WITHIN THE BATTERY CHARGER CABINET.
ONLY QUALIFIED PERSONNEL SHOULD ATTEMPT TO ADJUST OR SERVICE THIS BATTERY
CHARGER.
INTRODUCTION
Return all replaced components to your service center.
The following sections explain how to replace each component. After replacing a component, be sure to:
1) Reconnect all leads exactly as they were removed.
2) Replace any heat-shrink tubing if any old tubing was removed.
3) Retighten all connections
4) Replace covers.
Preparation
Please follow these steps before removing or replacing any component:
Disconnect the battery.
Disconnect the AC power.
MAIN TRANSFORMER
Use the wiring diagrams in the back of this manual to help identify wires connected to the transformer.
Removal
To remove the transformer:
1) Remove the AC input wires from the 3 terminal input blocks.
2) Remove the transformer control voltage wires from the little glass fuse holder.
3) Remove the secondary leads from the SCR/Diode Blocks.
4) In the back compartment of the charger, remove the bolts (as many as 6) that hold the transformer to the charger
frame.
WARNING: The transformer is heavy. Use appropriate equipment to lift it.
Replacement
To insert a transformer, follow these instructions:
1) Place the new transformer into the back of the charger, taking care of the transformer’s pigtail.
2) Replace the bolts that secure the transformer to the charger frame.
3) Connect the AC input wires onto the 3 terminal input blocks. Do this by pre-bending the wires and trimming the
double leads (wires #2 and #5) to the same length. The purpose for doing this is so that when you install the
double leads into the terminal block, they both get properly secured when the screw is tightened down on them.
4) Be sure that all wires being connected to the terminal strip are bare. Make sure insulation is removed from the
wires for good connections.
5) Avoid placing the A phase primary leads near the top panel’s mounting hole.
