Parts Identification

Hi everyone,

I’m trying to repair my alternator and I would like some help identifying the electrical components.

The regulator has the following markings “T518 L4”. I’ve tried to google it but can’t find anything.

I’m not sure what the item is with the marking “23-95”.
I’ve tried measuring resistance but don’t get a reading. I’ve also done a continuity test and the circuit is not closed.

The second component would appear to be a capacitor.

As to the regulator, it will be quite difficult to source any individual parts through electronics suppliers - possibly not impossible, but barely worth the trouble.

Take it to an auto electrician or your Land Rover service centre.

I agree. There are components that may be difficult to source as their part numbers may only mean something to the manufacturer.

“23-95”.

week of june first, 1995 ?

A quality image of all the markings would really help, the manufacturer's logo is often important to fill in the missing bits of the part number.

Alternator regulators are pretty stock parts - have you tried eBay for the same or similar alternator?

Date codes are YYMM in my experience, not MM-YY

usually YYMM on land rovers ?

the OP asked what it was. the black box with the unknown code of "23-95" that black box with wire is a capacitor.

the number appear to coincide with the date on the label, but that might just be coincidence.

I'd be inclined to scrap the board and create a circuit suitable for the task from scratch. I'm sure you could find plenty of examples with a google.

Thank you, this advice will come in handy. It made me understand something, and it is that I never knew before.

There must be a Land Rover forum where someone can spit the numbers from the top of their head.

Thanks everyone for you feedback, I’m going to try reverse engineer this circuit.
I know the output is about 13.8V to 14.2V - will confirm.
I also know the max A of the alternator is 65A, so I’m 99% I can find a replacement regulator for it.

As for the Cap, thanks, I will google how to test caps and see if it’s still good.
It’s a sealed unit so if I break it open, I will have to accept it as broken.

Thanks again.

Mind you, they're pretty cheep on ebay.

See!
