1982 Frame Off Restoration

[SupercoolBill]

This is all new territory to me.
Electrical box pulled out.

Picture of how I found it.

One overload jumpered (cooling fans??).

This relay cover popped off. Not sure what this does. Lambda relay??

Tam was bored so I let her get in to clean and disinfect the area. She wore a respirator and gloves and told me I should do the same.

I think the green one is rear defrost. A little dab of glue for that cover to go back on.

Tray emptied of relays, fuse block, and wiring


Tam blasted and painted the tray.

I dug out the relay/fuse kit I had bought from D-Ind.

I climbed back in the torture chamber and started cleaning wiring, relay blocks, etc.

A couple of the fuses came out pretty hard.

One fuse was a bit melted.

That makes sense...probably has a timer circuit built in.

The new overloads I got from had studs instead of slide on connections.

One end of these says "batt" and the other says "aux". Basically line and load. I'm not sure if the orientation is that critical or not. I matched the orientation of the overloads with the old ones. Hopefully I'm good with how I have them wired.
The ring connectors are a bit more of a pain to deal with but are highly recommend over the spade connector ones.


Things going back together. All relays got dielectric grease on the terminals.

I retaped the wiring. Everything back together.
Anyone know what the relay base with no relay in it and what the relay base randomly part way up the harness go to? Maybe stuff for automatic transmission cars?

My notes on the overloads.

While I was doing this Tam installed the injectors and D-Ind injector retainers.

The one relay you're missing is the interior light delay for the courtesy lights. The random socket towards the rear is for a hot start relay. When the cars were new they were not equipped with anything installed there.

So those wires are ran but not used for anything?

I think they copied what Volvo did. After I designed my hot start relay, someone found a Volvo hot start relay and sent it to me. It basically did what I designed but it modulates the CSV.

"This relay cover popped off. Not sure what this does. Lambda relay??"

That relay on the right end of the upper row with the green cover is the rear defogger circuit timer.

The relay next to it is the Lambda relay. Check the wiring diagram or relay diagram to be sure.

Note the Lambda relay is NOT interchangeable with the other relays that look similar to it. If you use the wrong relay in the Lambda socket the system won't to into closed loop mode.
