Model 1022 Alternator

Postby Dirk on Thu Mar 13, 2014 9:11 am

To someone at Ample Power:
For the past 25 seasons my Model 1022 alternator has been working faithfully on the Universal Model 25 engine in my 1986 Catalina 34 sailboat - until last summer when it strangely got very hot shortly after starting the engine after being at anchor for a couple of days. (Have an 85 watt solar panel to help keep the batteries up while at anchor) smoke came out of the engine compartment - (coming off the oil on the outside of the alt). The alt normally gets quite warm when it is putting many amps back into the battery, but this was much more heat than normal, plus the amp meter was reading 5 amps or so when it should have been up around 45 amps or so. We idled along slowly for about an hour wondering what to do since we were many miles from the closest port. Then the alt cooled down and showed it was putting out amps again, (30+) and by the time we got to our destination the alt and charging system was working just fine. And it continued to work fine for the rest of our cruise which was another 2 weeks and probably another 10 - 15 hrs on the engine.

Sooooo,
Now that the shadow of doubt has been cast, I want to send the alt back to you for diagnosis and possible rebuild. If it needs rebuilding and if it doesn't cost me an arm and a leg, my thinking is to purchase a new one from you and keep the old rebuilt as a backup.

The regulator is your 3 step regulator model 1021-A purchased in 1990. The system has worked wonderfully all these years and my AGM batteries last a long time, Last new ones installed in 2009. Do you advise to upgrade to a newer smart regulator at the same time, or "if it ain't broke, don't fix it"

We are great lakes sailors and cruise the North Channel of Lake Huron for 8 - 10 weeks each summer. Because of the remoteness of the area, I must have systems I can absolutely depend on,

Your thoughts?

Overheating and recovery for an alternator is unusual to say the least. Perhaps there was belt slip which can heat up the alternator front sheave and thus the alternator itself.

In 1990, the #1021A regulator was great technology, but it is as dated as the computers of that era. Either the NS2 or the SAR V3 will improve charge rate and extract more life from the batteries since the temperature compensation and charge algorithms are improved.

Rebuilding the alternator will probably cost about 1/2 of a new one. But do you really need a spare? How old will you be when you may need it? Another 25 years?

So, if I have my model 1022 rebuilt, it will be the least expensive but reliable way to get up and running again? If so, then do I just send it to you and you will take it from there?
