The heater in my engine compartment does in fact work when I hook up directly to the battery. Unfortunately it does not work when I pull the red lever on the floor in my cab. How can I check if I have a correct circuit?
Thanks in advance. |

This circuit works as a switched ground. The lever grounds the circuit. MAKE SURE that all the connection and contacts are clean.
The trace wire runs through the tunnel and then into the pin harness at the regulater plate. You can uplug the pin harness and then check for continuty with a DVM. If that rings out you then need to check to check the trace on the regulater plate. More than likely the connections are dirty. Check those first. |
