SECTION 1ELECTRICALTROUBLESHOOTING1.SYMPTOM12-volt DC loads are inoperative from battery 1.power, but function properly when vehicle isconnected to 110-volt AC power.COURSE OF ACTIONCheck auxiliary battery terminals. Are theyclean and tight? (Yes) Proceed to Step 2. (No)Clean and tighten as necessary.2. Check auxiliary battery voltage. Is battery fullycharged? (Yes) Proceed to Step 3. (No)Recharge or replace as necessary.3. Disconnect vehicle from 110-volt AC power.Check for 12 volts DC on Wire J* at the circuitbreaker in the auxiliary battery box. Is voltagepresent? (Yes) Proceed to Step 4. (No) Proceedto Step 5.4. Check for 12-volts DC on Wire J* at the loadcenter. Is voltage present? (Yes) Checkconnections at load center for tightness andcorrosion. Tighten and clean as necessary. (No)Troubleshoot Wire J to determine the cause ofvoltage loss. Repair or replace as necessary.*10, 8, and 6 gauge wires are not imprinted. Codeslisted for heavy gauge wires are for wiring diagramreference only.5. Check for 12-volts DC on Wi re A * at the ci rcuitbreaker located in the auxiliary battery box. Isvoltage present? (Yes) Proceed to Step 6. (No)Troubleshoot the circuit back to auxiliarybattery to determine the cause of the voltageloss. Repair or replace as necessary.6. Reset the circuit breaker by removing Wire A*.Then reconnect Wire A.1-11
