Right then, as you all know ive just put a 1.8T in my Mk2 running an 8v starter, and its all up and running. Problem is, i haven't wired the alternator in yet ! Now, as R.J has told me previously, the plug on my alternator needs to be wired in to the blue wire on the lighting loom, seen here - Thats all sorted. Now, i still have the alternator wiring which was running the 8v. This consists of - * One thick Red wire and one thin blue wire, which bolt to the alternator. * On the same loom it has a thick Red wire which bolts to the starter motor, and a black wire with a ring terninal on it. Im sure im doing something wrong, as when i have all the wiring wired together, the starter motor stops working ? But when i disconnect the alternator and attach this to the battery, the starter works fine. Have i wired this in wrong ? Any step by step help would be great. Cheers.
sounds like you shorting it out some how the mk4 alternator has one live and plug with two wires will be one in you case as i was looking as my tdi the second wire on mine is for the rev counter do you have the blue wire to the same terninal as the red wire the blue wire should go to one of the terninal on the plug or second small stud terninal in you case
Cheers for getting back Mushy. The blue wire is connected to the smaller terminal on the alternator, and the red one is connected to the bigger terminal. Also, the red ring terminal on the same loom connects to the starter, and there is also a black wire with a ring terminal ? Where should this go ? Cheers.
is the above how yours is wired the big black is the battery live the plus the red from the alternator what looks like a black wire with the red from the alternator is the blue wire in a black sleeve and go's to that plug in your picture
Yea, i'd say the alternator side is ok. The starter motor on mine has - * Black/Red trigger wire * Red spade connector from alternator wiring on the starter. * Black wire, sorry i meant spade connector - Not too sure about. Earth maybe ? Looks like i maybe missing a constant feed to the starter motor from the battery ? ...
yes the red and black is from the realy/ignition switch you may not have the small black wire with spade but yes it's a earth
hmm black wire spade? you shouldnt have that as i didnt put it in your loom when i made it, as above its for cold start on k-jet. you should have: chunky wire from battery -> starter 13mm stud chunky wire from starter -> alternator 13mm stud chunky red/black spade -> starter pin 50 thin blue wire spade piccied above -> alternator 2 pin plug pin D+ or pin 2 thats it!
Now that's why I hate wiring lol You always end up ripping out a ton of old wires you don't need from some ice build gone wrong Just as well your on the case john I did think he should not have the black wire on the starter being a driver to start with
Cheers R.J Basically on mine i have - * Chunky wire from alternator to starter (Plus thin blue wire to alternator) * Chunky red/black trigger wire * Thin blue wire piccied above * Thick black wire with a ring terminal on it ? There doesn't seem to be a power wire from the battery ? I'll get a few pictures up later.
spade or ring chap? spade is the type of connector on the thin blue wire and starter trigger, ring is well, a ring shape you should have battery +ve wire to starter stud, and one from same stud to alternator stud. then a blue wire from the spade to the alternator 2 pin plug, thats it!
