No scratches, gouges, or burrs allowed in the SCR/Diode Block contact area.

No oil, dirt, paint, adhesive or other foreign substances are permitted in the contact area.

Disconnect the battery and AC power before testing the diode.

You will be testing the diode to see if it is shorted.

Disconnect the three phase input wires to the SCR/Diode Blocks.

Use an analog meter set to its X1 scale, or use a DVM set to its diode scale.

Connect the meter's negative lead to the input connection of the SCR/Diode Block.

Connect the meter's positive lead to the - bussbar.

If you are using an analog meter, it should read close to 0 ohms.

If you are using a DVM, it should read a .7V drop on the diode scale.

Reverse the wires on the meter.

Warning: Disconnect the battery before testing the control transformer.

You will be testing the wiring of the control transformer for continuity.

Lugs 1 through 5 are located at the front of the control transformer, with lug 1 at the top.
