Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures

2. ALL units in the rst few days of use should be checked for mis-wiring or loose connections

1. All/tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 ohms per-volt DC, or

greater.

2. Check all connections before replacing components, looking for broken or loose wires, Failed terminals, or

wires not pressed into connectors far enough.

3. Resistance checks must be made with power cord unplugged from outlet, and with wiring harness or
