Terminal or relay?
Relay may well be either the 'X' relay which basically reduces current through ignition and turns off certain functions when cranking or it may be the flasher relay.[only 3 terminals]

Post by: somolovitch3 on January 04, 2008, 05:03:16 am: IIRC, load reductin relay drops out the wipers, the heater fan, rear defrogger, and......

Need it....not if you turn EVERYTHING off before shutting down vehical.

I personally get in there and rebuild the fuse/relay plate so the following happens when I start my diesel:

1)When the Alt light is on, there is NO power except to the glow plugs
and the key's input so you get just the 50 terminal "hot" when you
turn to the start position. (Thats right, no radio, lights, wipers,
heater fan, nada!)

2)Once the Alt light goes out, THEN there is power for evey thing else.

Yes I know what a PITA! Does make sure whatever power I have goes to the GP's and starter thou! :twisted:

And yes it does take a few extra heavy duty relays, makes trouble shooting quite fun, and when a conection goes bad, well, like I said PITA!

Can't remember what the little term is for, GP light? maybe? :roll:

Post by: cal on January 04, 2008, 09:11:41 am: so what you're saying is that the relay takes all the power and dedicates it to the start?

Post by: burn_your_money on January 04, 2008, 09:13:18 am: It basically cuts power to all the unneeded accessories when starting the car. Only the essentials get power. MK1s already have a load reduction relay (x relay) wired in

Post by: cal on January 04, 2008, 11:13:11 am: that's brilliant guys :) so in theory i only need the glow plug relay out of the mk2 and i should be set to swap everything over.

are there any diy's for conversions into petrol's?

Post by: somolovitch3 on January 04, 2008, 06:48:41 pm: The x relay as I said drops out some of the power hungy stuff, as I also said, I "remodeled" mine to alow no power except for starting.

For gasser conversion, From gas to diesel, Yes?................

Get engine harness, front (I don't rember how they did this {Tyler?} The dash harness or what ever it's called, relay plate/fuse box for the year of the motor you are installing. Then drink more beers, you will need them!

Decide what featuers you want, and build them in.

Fun, HELL YES!!!!!!!!!!! Okay so its also a little pita. SO WHAT?

yes i am a bit crazy............ YOU will have what you want in YOUR vehical, because thats what you wanted!!!!!!!!!!!!!!!

Sorry, got a bit over well-meaded.

Gods I love VW elctrical work!!!!!!!!!!!!!!!!!!

Enjoy!!!!!!!!!!!!!!!!!
