Alternator

[mercury6]

Looking for some help with regards to a new or higher ampage alternator for my 62 series, what's out there?

Running 2 sets of spotties, 1 set of fog's, stereo (2x amps), alarm and immobilser, and later fitting a fridge.

At the moment, I think the stock one is struggling with the demand, but not sure... sometimes I have had to whack the battery on charge overnight just to be sure... start car, it will sit below 12amps for a while, then slowly gets above (just)

May just be the battery getting old how new is it have you had it load tested whats the alterantor putting out and if you see a auto elec he should be able to test how much the spoties and so on are draining out of it.

Are you running and external or internally regulater alternator?

I believe the externally regulated unit is approx 55 amps, however the internally regulated unit is 85 amps.

pretty easy to swap over, I did my 60 series and just used the plugs from a 75 series.



Before spending big dollars, i would look at the condition of the brushes, if they are worn the unit may not be charging to its full potential.

If you have to get a new alternator, shop around, I got mine via an auto elect mate for $240..00 brand new. watch out for units that have slightly different vaccum pump fittings.
