Hi Guys,
Ok a while ago I had some issues with the fusible link to the Alternator burned up, so as a quick fixed I joined it back up again and it has worked for a while, took car to work today and the alternator light was flicking on and off, got to work to find the fusible link had popped again. So after work in the carpark I put a piece of wire in there and before you say OH NO YOU CAN'T DO THAT from all my research a fusible link is nothing more than a piece of wire smaller than the wire used in your car with a special rubber coating that doesn't burn, so selected a piece of wire of lesser gauge than the main wiring. Note the battery has a hydrometer built in and its black/green/clear, the battery was showing black which means its in need of charging. Put my meter across battery and its 12.68v, start car up and check wire is not hot and it was ok, put meter across it and rev car up and comes up to 13.2v, that's not enough to charge, I remember my father years ago saying Chrysler charging systems are weird and he could never work them out, so I get home pop the hood and the blue wire is melted, put my meter on and its now charging at 13.9v when you rev it up, so that's more like it! maybe 14.2v would be perfect. Now the charging system is either clever than I think or Chrysler has a weird system, anyway I am thinking this, the alternator is not the one that came off the car, I noted the other day you can get a couple Alternator options on current for your car, could be wrong here but I think it was like 60,80 and 100, I have no idea what the Alternator I put on is can't find specs on it. I am suspecting Chrysler set up the fusible links to what Current Alternator is fitted in the car, so my battery was getting a full charge into it and the current was more than the link could handle, that's my thoughts, everything in the car is working as normal.
Old Alternator has a round yellow/bronze colored tag on it.
This is the Alternator on my car now - Premium Quality Remanufactured Alternator mopar part # 3438713 5305 ~ 3035
I have spliced in a 100amp fuse, I hope that is not to small. If 60 amp alternator that's all that can come from that line, if more current is required it will come from battery and the battery will go flat. Head lights 10amps, Ignition 7amps, radio, heater blower and rear demister, that rear demister could draw some amps, maybe 10/15amps
Thanks
Bruce
