^•Always use a new circuit breaker with the same amperage as the
old one. If the circuit breaker immediately trips or the component
does not operate, the electrical system must be checked.

5. Connect the negative battery cable.

RESETTING

» See Figure 118

1. Insert a thin object into the reset hole and push until a click is heard.


2. Using an ohmmeter, check that there is continuity between both ter-
   minals of the circuit breaker. If continuity is not as specified, replace the
   circuit breaker.

REPLACEMENT

Locate the relay and pull it from its socket. Most should pull directly out,
if not check for clips on the side of the unit, release, then pull. Install a new
one and check its operation. Fig.^118 Resetting a circuit breaker
