After removing bulkead connectors to clean no start

If the connectors were cleaned , the female part may need to be crimped slightly for better contact. Beware, the contacts are often brittle, due to heat cycles and corrosion. They may not have the ability for a tight connection. The Packard 56 terminals are rated at only 5 connect and release cycles, so the best fix is replacement with tinned terminals from Waytek Wire or other sources. The tinned connectors reduce corrosion. The connectors are also in wire gauge, for the wire used, so one size does not fit all.
