Foolish mistake

doriz · Jun 12, 2015

Evening all,

I managed to put the battery on the wrong way on my 200 tdi the other night as I was rushing and my eyesight is on the fritz.

Is the alternator fried, is there a fusible link to protect against muppets like me or do I need a replacement alternator or diode kit?

If I can fix it, I can spend the money on new glasses instead

think it could just blow the diodes.

i presume you put it the correct way, started it up and the bat warning light stayed on or some other error?

It's like you were there, that is exactly what happened.

Depending on what Alt you have fitted look at getting a rebuild kit for it rather than replacing the whole alternator. If it is an A127 (check first) you can get the kit for £20 ish and that will contain replacement diode pack / regulator.

Fortunately this is a toy and not my daily driver so I'm going to take it off today if the weather behaves. Once I know the type it will make it easier to assess the task.

It did look rough from underneath but I would like the opportunity to swop out the part and have the satisfaction of rectifying this faux pas myself.

Don't know if this helps but seems cheap enough.

Many thanks, I'm going to take the alt off in next hour even tho it's belting down and see which model it is. Suspect I couldn't fix it for £30, shame about postage.

That was fun, soaked and covered in oil after removing the air box etc. the alt is an A127 3 pin manufacture date 03-91 which is the reg year.

Might be better to order a new unit.

Decided to strip down the alternator and it's beyond repair. It is the original unit 24 years and 200000 miles. the bushes and shaft are badly scored, it's full of grime. If I knew how to post pics I would.

Time to find one on the net, many thanks for all your comments.

pretty sure you can buy all the parts to repair. cost it vs a good quality new one

new are about 60 pound, not too bad a price considering the amount of time and effort you have to put into refurbing one.
