Could you please Private Message me with the local Baltimore rebuilder mentioned. I have my Motorola Alternator needing a rebuild.

Thanks,

Talking

You are playing with fire .....literally.

if you use a non-ignition protected alternator ina space containing gasoline there is a very good chance you are voiding your insurance.

It is against the law here in Canada under the Small Vessel Construction Standards TP1332E

It is also against the law in the US as per Title 33, Code of Federal Regulations 183.410

I've used 'Mamocks Motor Electric' in Annapolis and was happy with the service. Mamocks Motor Electric Annapolis, MD | 314 Legion Avenue
There is this place in Baldamore but I have never used them: ******************** Free Starter, Battery or Alternator Check - Home

Re: A4 alternator?

After reading this thread I can't beleive that some people are putting automotive equipment in their engine rooms. If you don't know what you are doing hire someone who does please.
If you are running automotive alternators or other dangerous equipment please stay well away from me and my boat.

Re: A4 alternator?

Hey, Norah, I can't believe that you're replying to a TWO YEAR OLD POST or that you've never seen automotive equipment used on boats.

Don't worry, you've scared everyone away from you and your boat.

Re: A4 alternator?

I wanted a larger alternator than the 35 amp one that came with my rebuilt A-4 so I purchased a 55 amp one from Moyer. It is a good alternator and keeps our batteries happy. We have the "old" one as a spare. I would recommend taking a look at Moyer's web site.

Re: A4 alternator?

Downeast 450 ......I was thinking of doing the same thing. Was it a simple bolt on replacement? Using the same bracket and belt?

Jimmy,

The same pulley but a different belt. The belt is listed on Moyer's site with the alternator. Direct bolt on and wire up. I also purchased an Indigo Electronics Atomic 4 Belt Tensioning Device.

It was a good decision. I am happy to have it. Well worth the money.

I do not understand why anybody would do anything but and off the shelf Brand New Leece Nevill WHICH is and exact replacement from spidermarine among others



Fits in as its the same case and IMHP anything over 51 AMPS is waste with the tiny belt and tiny drive unit
