Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

2 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

POST 2Original post

Turn the switch on and check the voltage at the body contacts. If no volts check fuses & relay. Check the resistance in the top grid. If open check the contacts/wires by the bayonet mount. If both check out then check the alignment between the top contacts and the body contacts as you mount the top.

This is a source reference. Confirm exact model applicability in the original material.
