LT-1 Alternator

So have any of you LT-1 guys needed to replace the alternator in your boat? If so, where'd you get it and how much did you pay. Talked to skidim today, they want close to 300 for a new one. I'm trying to find a marine alternator, with a bit more amperage that fits the lt-1, if anyone has suggestions please let me know. Thanks in advance.

Nathan

Go to a shop that rebuilds alternators, starters and other motors. They will (or should) be able to do it to marine standards. It'll save a lot of money. They may be able to increase the output, too.

I agree with JimN.
I had a non-marine alternator in the past go out, it was going to be $300+(I am not a fan of autoparts rebuilt units).
I was refered to a guy by a friend that rebuilds them. He replaced everything inside including bumping the amps up a touch, if I recall it was $120.00. He was able to do ANY alternator/starter.
A good find.

Nate- when you find a rebulder, ask them which dealers and repair shops they do them for. If they list most of the dealers in town, go there.

here's one i found in my home town http://www.barbinelectric.com/indexx.shtml
they seem to be pretty good. a buddy of mine recommended them, he's in the auto repair buisness. so as soon as i get the alternator out i'll be dropping it off there. thanks for all the input and help.

Nate

The alternator on your engine is 55Amps. The wiring between the alternator and starter solenoid as well as the ground from the alternator is sized for a 55A alternator. If you bump up the alternator output, you also need to increase the wire size appropriately.

Did they run a test on it afterwards for volts and amps? Did they tell you the results of that test?

I went to arco marine. They were incredibly helpful and knowledgable - they don't know the boat, but given the engine and a couple of questions they zero'd in on the part. They knew the history of the part and even recommended the current replacement (which provides more output 70amp). Evidently they have been doing this for a long time.

Make sure you mention if the pully is V or serpentine - different part number. Arco part for 1995 LT-1 (exact replacement 60055) - current late model replacement 20820 (with 65mm serp pulley).
