super urgent! Changed the starter, now wont charge
« on: 10 July 2009, 10:52:58 »
Hello guys,

My 2.5TD elite starter went the other day, changed it last night, starts lovely but now battery light on and wont charge!

I bridged a cable between the small nut (feed to alternator) from the battery, laboured the engine, but no difference on the volt output...

Desperatly need this for today  :-[, so any help is much appreciated  :y

alternator main lead goes from alt to the main fat lead going to starter, then to battery.

Cheers The Boy, I rented a van in the end :D

Further tests would indicate fried alternator, which may have been me then when I was pissing about with the starter  ::)

Time to kind an altermanator then!  :y

Chances are you may only have fried the regulator, in which case relatively easy to replace

Right, well changed the alternator last night, started it and no change  :'(  :-/

Battery light still on and eventually turned itself off when it ran out of battery...

Didnt have a multi meter at the time and it was late so didnt really have a chance to check any thing.

Do the TD's have a charging relay I may have buggered?

ok, so did some more tests tonight, little wire has 2v coming out, big one... 0.05v!

BUT, tested the 'old' alternator on the windy gun, 14v no probs... can trace the big wire from the alt on the car, but it must go somewhere before the battery?

Do you have 2 large cables going to starter (as well as 2 smaller ones)?

Yeah, on the starter, 2 big ones (one to the battery) and 2 small (which seem connected?)

My electrical knowhow is not so strong at this level!

No, 4 studs on the starter solenoid, 2 big, 2 little.
4 wires, 2 big, 2 little

The big battery feed goes to the top big stud, I have forgotton where the other one goes (but that has a big wire going from that into the actual starter)

The 2 smaller connections cant get confused as ones 8mm and the other 10mm :) (although they seem to join).

I gather the starter earths through the body? As I said its starts/turns over fine, the engine does do a couple of 'skips' initially when running, but fine after 30secs or so...

No, the big wire from alternator has to go to same stud as wire from battery - basically, the idea is its a single wire from alterntor back to battery, but shares starters wire from starter to battery.
