Plug on rectifier

[LWH]

are there different plug ins for the 1985 Interstate mine looks like one plug but I see some have 2 plugs

[DaveO430]

Some have a radio noise suppressor connected inline with the reg/rec but there is only one connector on the RR if it's OEM.

thanks for your Help

Many 1200 owners have followed the route of the EC 1200 harness ( which I installed about 14 years ago ) and removed that Rect /reg plug and hard soldered and shrink wrapped those connection wires too..
They have the same design flaw as the meltable 3 yellow wires plug ... up to 70 VAC going thru a plug designed for 12 V DC.

That's not the issue. Voltage is not the limiting factor - you could put a hundred thousand volts through that connector and it would work just fine.

The issue is current. Current is what heats things up. And the more resistance there is, and the more current there is, the more heat is generated.

So we know that we have a large amount of current being sent through that connector, and it works just fine - until any dirt, oxidation or corrosion gets into the connector and starts causing some resistance. This causes heat, which causes more oxidation which causes more resistance which causes more heat, and so on...until the connector melts.

My bad ... you are quite correct ... its current, not voltage ..

but many of my 1200 friends have hard soldered both the 3 yellow wires plug, and the (iffy) ones at the rect/reg

Yes, it's a common fix for all the four-cylinder wings, mine included.
