any shop mechs got a number for a alternator?

[carboncow]

i'm got a Volvo Penta AQ145A and am looking online for a new alternator, which many do by part number...and i don't know how to aquire the part number...<br /><br />it's a Paris Rhone and i've seen cheap Delco replalcments for the Paris Rhone, but need to confirm the part number for a 55 amp ride...<br /><br />any thoughts on the differeces between the hard to find and expensive paris rhone and the delco replacments?<br /><br />any help?<br /><br />Thanks.

You have an 858838, or 841765, or 841762, or 858839. <br /><br />Sierra replacement number is 18-5970 - 55 Amp<br />or 18-5971 70-Amp<br /><br />or 18-5972 90 amp<br /><br />They usually run about 250 bucks. Or you can take yours to an automotive alternator rebuilder and they can repair it for a fraction of the cost. Yes, they will understand it is a marine unit.

thanks for the help. i've got one good auto electric guy in my small home town...and i didn't like his rebuild price on a paris rhone...<br /><br />interestly the delco rebuilds were only $159 from an online company (free shipping)...but they referenced part numbers. thanks for you help.<br /><br />i actually have a high voltage issue (approx. 16v) so i am thinking of just replacing the VR first...do you agree or should i assume that the brushes may be worn and 1/2 the problem?

A grounded field wire from the regulator, or grounded within the regulator itself will cause high voltage.
