Charging fix

[Bob]

74 Charger, intermediate charging problem
This was driving me crazy. The 2 prong plug that plugs into the voltage regulator, the holes were a bit enlarged because they are a split type connector. Squished them together a bit and everything is fine.
Maybe this will help someone else.

same happens to ECU plug... if someone wants to know

same happens top ECU plug... if someone wants to know

Oooh oohhh  I want to know!!

i think thats my problem with my ECU right now.....will crank, start then immediately shut off. (electrically)   Wont stay running unless I "wiggle" the connector.....will stay running with no trouble.  Until I shut it off & try to restart it.   Started happening last fall

aaand, distributor plug too

advice: adding some dieletric grease will help on save some resistance and againts rust

I'm checking a "damaged" ECU. A friend of mine fixed an orange unit what supposely was damaged... removed the backing susbtance/isolator and  noticed a ground strap inside the box was loosen from chassis... solded back and VOILA orange box fixed.

Check the good ground between pin 5 and chassis ground, must have GOOD continuity. Pin 5 is the one right in front of the unexistant pin.

While squishing them back together works in the short term keep an eye on it. Most compression connectors have a limited insertion cycle lifetime. Typically with the spade type, once they loosen up the metal has become fatigued and they will do so again in short order. Also note that with marginal connections they will have higher resistance and if they are in a high current application it will end up overheating and charring the connector on both sides.

Those connectors / replacement plugs are available at the parts store... sometimes on ebay also.

They're also known for corroding internally.   I had a problem overcharging years ago... the parts store didn't have that connector so I hacked it with some female bullet connectors.   See below for what it looks like 30 years later.

Is that a hack you applied in High School - That stayed with the care through the other owners?

Yeah...   seeing how it hadn't run since about 1981 anyway
