Alternator Help
I need to purchase a new one for the boat. The part number I took off the old one is 98555. Tag says it's a 55 amp. It has four wires. It's a vintage 1986.
The vendor sites I've been on here don't show this unit. If I plug this number into the Mercruiser product line nothing comes up, not even an alternate.
Help!
Thanks, Dave

The rule of thumb used to be 55 amp for carbureted engines and 65 amp for EFI. Arco makes new replacement units if you want to stay with the 3 wire set-up. The one wire Delco mentioned by kennyo is a self-exciting unit that works fine in many applications.
Is your old one a Mando unit?

I removed the alternator yesterday and took a closer look at it, it's a Mando made in Korea. After looking at it closely I see that the pink and purple wires have a break in the insulation outside the shrink wrap. I see that the purple wire goes to the back of all the gauges. I have been chasing tach gremlins this past year. Could this bare wire, even if it's not connected cause tach problems? What does the purple wire do?
Thanks, Dave

see your from Lancaster. I would contact Al Conti at Conti electric in Buffalo. He can rebuild your alternator for much less than a new one and when its done you can be sure its right. Dell electric in Hamburg is very good as well. I got tired of buying rebuilds from Napa or Autozone and have them fail in less than a year. Im from Angola by the way.
