The story goes....My volt meter has run at around 13 volts all the time until I stop at a red light or get stuck in traffic with the head lights on where it drops slowly to about 11 volts. Never worried about it as battery has never got low on charge.
But yesterday I got my air con running and the volt meter ran continuously at about 10-11 volts so I thought this afternoon I would investigate.

I removed the part which I assume is the regulator to check the brushes, they looked ok , I thought the box would just have the leads from the brushes to the the terminals inside...Wrong it had three prongs into a circuit board which pulled out when I opened the box.

I have removed the alternator but it has no make or part number on it, just a sticker label with a barcode.
What is the small part called I removed with the brushes on. And can it be replaced separately . I went to local parts place but they can only source a complete alternator. They have no listing for an XJ6 prior to 1986 XJ40.

I need to supply a part number. I do have one supplier from the local auto electrician, but can't get there until Monday.

Any input would be appreciated.

 

Maaaate, that is streching the memory, but Motorola is pinging the active cells.

Dont mess around, contact Ashdown Ingrams, Goodle your location on their website and go see them. They are a godsend to me down here when I need the "right info at the right time".

Take the alternator to them and get what you need.

It looks tired to me.

 

Thanks Grant, Ashdown is the place the auto lecky told me to go to Monday(less than 10 minutes away). The internals look pretty well past the best,pictures make it look better than it is.
I will start pricing new ones tonight and see what they say on Monday.

It looks like the date on the sticker is JAN10/05, would I be reading that right?

 

Thats what I also deciphered, and I suppose 10 years is fair.

They also have parts, but I really would think twice about rebuilding that unit, and 65amp is a tad low with a/c, etc.

 

Clarke mine has Lucas England 20ACR if that's any help...
Copes quite well with a/c etc...

 

Thanks guys, I will have a look what is around.

Grant, what amps would you suggest?

 

Around 75 or better with lectic fans etc.

The clutch on that compressor draws about 7 amps, so when you go through the car it all adds up.

 

A few options available locally on ebay.
The second one is the same as Jim's (Daf11e), remanufactured from US.
The last one is the same as mine and in Qld, only one that mentions amps.(can get it by courier overnight Monday),bought from them before.

I assume anything listed for series 2/3 will fit as some of them cover 1/2/3.

Sounds like your on to it Clarke.

The only thing I could think of if you are going from 65Amp to 75Amp the cabling would have to be good for an extra 10amps.

I have heard that some of the lucas cabling was borderline sitting on max CCC (current carrying capacity) for a particular circuit. This was to save costs at the factory.

Maybe some of the more experienced guys could confirm but just worth looking into so you don't risk having a puddle of goo under your bonnet after the upgrade!

If the wiring has an AWG or mm2 we could work it out to be sure.

Just a thought

 

I would be looking for a 90A replacement even if we have to swap the pulley and or make a new bracket

Can you post the dimensions of the mounts so we can see what fits
Hopefully a common local car will have something that will fit in a higher amperage as well

The dimensions I need are outlined on page 88 of the ashdown alternator cat

The wiring all looks original except the red one.




Here are the dimensions.

 

mmmm.....hard to tell from the picture. Do you know if the wire has an AWG or mm2 rating stamped anywhere on it?

Anybody know if the original cabling for this series is good for 90Amps? May be fine but just wanna be sure.

 

Just need to run an extra cable to the battery to double it up and be sure

Im guessing early dunnydoor v8 (90amp) will fit he brackets but need to check

Cool sounds like a good idea James.

 

James has it sorted.

I was thinking Coon XD etc.

That Jag set up is "standard" Lucas mounting, NOTHING specific to Jaguar.

Bosch did make a unit in 85amp a looooooong time ago that was a direct fit, coz Bosch then was more reliable than Lucas, duh. We sold heaps of them at my employ at the time.

The Ebay ones should be OK, its just that mounting arrangement you have to watch.

The V12 unit has that adjuster lug on the other side of vertical, coz the alt is on the RH side.

Some aftermarket have that adjuster lug on both sides of vertical, thus making them LH or RH mountable (big word for me), but I have not seen them for a while.

If it were mine, I would give it 12 hours and ask Ashdowns in the morning.

The extra +ve wire to the battery is a MUST, thats all. The other wires will still be just fine, as the car will still only draw what it needs, just as it always has.

Add a GOOD heavy extra earth wire, just for giggles, does absolute wonders on the V12's, and YES Paul, the Goose got extra earths, haha.

 

Yep, the plan at the moment is to talk to Doug at Jagdaim in the morning to see if they have a bigger one in stock than the 65amp. And head over to Ashdowns for a talk to them as well before doing anything.
Most of the 85amp Holden/Ford ones I can see pictures of are mounted inside the bracket, my lugs have to outside the bracket.

Will see how we go tomorrow.

 

Would be surprised if Ashdown don't have one in a bigger amp range that will fit.

Its not a big job to weld a new set of lugs onto your bracket either.
Worst case I can bring the Tig/Plasma down to you place and get that done in a jiffy

I need to pickup a bottle of argon in Brisbane anyway

Lets see how you go on Monday. I have to swing by Bris Airport Tue morning anyway so we can do that that on Tue if you need to

Thanks James, I'll let you know how I go tomorrow.

 

Wow, all good stuff, even though on a different continent!


My electric issues continue. It looks like a falling domino thing. Latest is alternator related. My LT1 SBC has a huge 140 amp rated ACDElCO alternator. The 94 Cadillac Fleetwood Brougham had tons of electrics.


Issues. voltage dropped way down. Car stalled. Smoke from right rear corner of the engine bay. Stopped smoking. Car will not crank. Passing postman opines, an awful noise. My hearing aids not on! My limited audio doesn't hear it.


Suspect areas, to be checked:


1. Alternator gone bad.
2. Wire from Alternator to fire wall post gone bad
3. Connection of Alternator to post at post gone bad.


Dilemna:


Car in driveway facing road. I'd like it facing away from road. Go minto road and turn around then fix? Or fix in situ?


Apologies for hijack, but some might be useful to others.
