Car Forum / Volkswagen / Water Cooled Volkswagen Cars / December 200882 cabrio wiring
Does anyone know where I can find a readable wire diagram for an 82 rabbit cabrio. so far as much as Iv'e been able to check out is no head lights (will flash on when pulled at wheel) and no start. I am getting spark, but low or no fuel pressure. All fuses look good but I think it must be closer to an ingition switch but not sure where there connected. > Does anyone know where I can find a readable wire diagram for an 82 > rabbit cabrio.

Load reduction relay? do you have the Bentley manual? they don't have "wiring diagrams" per se but "current flow diagrams" that's about all I've been able to find that is complete enough to be usable however. nate  Signaturereplace "roosters" with "cox" to reply. http://members.cox.net/njnagel Run a wire to #50 on the starter. Briefly tap it to the battery pos. If it starts then it's prob. the ignition sw. SFC > Does anyone know where I can find a readable wire diagram for an 82 > rabbit cabrio.

Check the proper starter wires on the back of the fuse box. They will be thicker red wires with possibly black stripes. I forget now! BUT it sounds like the starter is working since you mentioned you get spark. So ign switch is a possibility if the gauges don't turn on when the ign is on. ign switch has to be on for the headlights to come on with the switch. But you get spark telling me that there is some power from the ign switch! You need to tell us EXACTLY what this vehicle is doing or not doing. Give us a blow by blow of what you do! If it is only a fuel problem, it might be the relay for the fuel pump. You could jump the proper terminals to get the fuel pump to run. > Run a wire to #50 on the starter.

If he is getting spark, then check fuel pressure next. Betcha it is fuel-related - and given the age, the relay as you suggest. Peter Wieck Melrose Park, PA Well it seems to be 2 unrelated problems, the not running problem is the timming belt is half shreaded so jumped time. Easy enough fix The no headlight problem on the other hand I've already checked the switch and load relay and there fine, so would I be right in thinking that something is wrong with the ignition switch. with the key on I get no power to the headlight switch , yellow /black wire ( there is power to red wire for the tail , marker & interior lights only, ) > > You need to tell us EXACTLY what this vehicle is doing or not doing. �Give > > us a blow by blow of what you do!

Sounds like a good guess, ign. switches on VWs are not very robust, can you find where column connects to harness and backprobe connector to confirm? nate > Well it seems to be 2 unrelated problems, the not running problem is > the timming belt is half shreaded so jumped time.

Signaturereplace "roosters" with "cox" to reply. http://members.cox.net/njnagel NOT the ign switch IMHO but like Nate said backprobe connectors to confirm and do it to both switches! The headlight switch should get power ALL of the time and not through the ign switch. So after you change out the timing belt, and I was "shocked" you got sparks <g>, check out the wiring at the battery and at the fuse box. BTW how did you check out the headlight switch? Ohm meter checking since it commonly goes bad too? ;-) Signaturelater, (One out of many daves) > Sounds like a good guess, ign. switches on VWs are not very robust, can > you find where column connects to harness and backprobe connector to [quoted text clipped - 20 lines] >>> If he is getting spark, then check fuel pressure next.

[quoted text clipped - 4 lines] > BTW how did you check out the headlight switch? Ohm meter checking since it > commonly goes bad too? ;-) I'm pretty sure the A1s/A2s I've messed with (two 84's, an '86 and an '89) only got power to the headlights with the key in "on" position, making me think that it went through the load reduction relay. Not sure if '82 is different or not. nate Signaturereplace "roosters" with "cox" to reply. http://members.cox.net/njnagel Not sure but I think the headlight SWITCH gets power all of the time and then to the headlights via a relay energized when the ign is on. Power would feed the running/parking lights even without a key in the car. I could be wong though and will have to check the Bentley! ;-) Signaturelater, (One out of many daves) >> NOT the ign switch IMHO but like Nate said backprobe connectors to >> confirm and do it to both switches!

As far as testing the headlight switch I put power to the one side and clicked the switch on and got headlights I guess I'll tear into the ignition switch next 100% right!! The load relay is turned on by the ign.sw. which powers the headlights etc. On starting it's turned off so all the battery power goes to the starter, ign etc. SFC > Not sure but I think the headlight SWITCH gets power all of the time and > then to the headlights via a relay energized when the ign is on.
