Delanair II

Delanair II
I did some work on my three fan relays last night. Pulled them out, cleaned the contacts and then replaced. Also cut out the wiring for the old amplifier as it is no longer used, replaced by new aftermarket one. All has worked well in the past. But now, with the key turned all the way on I can't get any blowers to work at any speed. Engine off I was able to get the blowers to work in the past. My wiring diagram only shows the three wires at cords H7/8 going off to the A/C circuitry (139). Is there a wiring diagram for the Delaniar somewhere I can get ahold of? Many thanks ahead of time.

After a short bit of sleuthing I found the following EXCELLENT posting - mostly by Jose. You are the man! Thank you again.

Didn't mean to leave Doug out. Yes, he is a MAJOR resource and contributor!!
I only cut the wires at the old unused amplifier. You can see it in the attached pic. Did I cut something I shouldn't have?? Also in the pic... Any idea what that relay is with the arrow pointing to it?
I can't find it on the wiring diagram but I know it's got something to do with the A/C cause it clicks when turning on the right hand mode knob.

It's a fan relay.
According to my 70s vintage Delanair Mk II manual the system used a stand-alone 'low speed' relay in conjunction with a 3-in-1 'main relay'; that is, 3 relays in one box. At some point in Series II production this arrangement was replaced with a 4-in-1 relay. The parts catalog gives the VIN breakpoints.

Then maybe there's a lower than Low speed. Does that mean I have a four speed? Nothing happens when that picks. I'm still trying to get that relay out of there so I can pull the can and clean the contacts. My electrical experience from 1st and 2nd generation computers (way back when) says that most problems are a result of bad electrical contacts - relays, connectors, plugs/jacks, etc. I've been going through the whole car with dielectric grease and burnishing tools where appropriate.

Hard to find now but decades ago a guy named Chip Lamb was reprinting and selling them. Keep an eye open.
I'll never let mine out of my hands but perhaps one day I'll scan all 88 pages and get it back in circulation.
