Which alternator 1500 1987 car and voltage regulator

Hello

Can anyone please confirm what the standard alternator is for that year, is it Marelli, Bosch?

Can the voltage regulator be changed in situ?

Is there supposed to be in place any heat shield from the nearby exhaust?

Many thanks

RDS

Alternator:

Voltage Regulator:
Depends on if you have ac and what connector is on it.

This is one for an 80-88 with AC or without AC.

Alternator cover:

There is suppose to be one and it will all depend on if you have AC and what alternator you have a Bosch or marelli.

For example this is for a Bosch:

Many thanks Napoli kid

i am in Napoli myself now funnily enough and viewing this on my phone so cannot easily view the links or check things at home- will do so on my return.

No AC on my car BUT as i am trying to fit the second cooling fan per AC cars, i might have to post a new thread for the wiring for that;unless you can tell me:
1 are both fans fed from one relay? if not how? how best to convert a non ac wired car to operate two fans?
2 what gauge is the feed cable?
3 is the alternator of a higher spec merely because of the need to operate two fans?

Many thanks

RDS, Did you ever get to the root of your hot coil / cutout after 20mins running?
I was following your post with interest.

Thanks & Kind regards Scotty

Re: Which alternator 1500 1987 car and voltage regulator

Hello Scotty

partially no in the sense that the holiday season and then a very heavy workload and then poor weather has stopped the experimentation but partially yes in the sense that i replaced the (missing, on separation of the joint) exhaust gasket at the collector flange and ran the car at idle for 45 mins (before a voluntary shutdown) without the car overheating or idling roughly and with 2-3 cycles of the rad fan cutting in and then out. (One of the theories i had was that the fan motor was causing a heavy electrical drain in use and now this has been partially discounted.

I also changed the spark plugs and checked the carb filter whilst at it.

However, I am not totally happy or trusting yet and was going to update the thread with all the things done...er that is when i do them! That twill follow when i move the project forward.

i am hoping that the escape of hot exhaust gasses in the engine bay made things too hot for the fuelling and/or the electrics but as yet, i am not convinces without more trials.

Does this help?

Have you tried anything?

cheers

RDS
