Now thats a alternator!
Nice looking unit for sure. Wide foot though won't work for me.
One thing you all haven't addressed is the difference between MSRP and actual pricing online.
For instance, a balmar 120 amp 6 series alternator has a MSRP of $979, yet can be found online for ~$660. Now I don't know if that makes any difference to you or not.
There seems to be 2 questions here.
Balmar doesn't make their alternators others do...
And they jack up the price
But far as I know, the mafufactors of Balmar alternators are essentialy the same ones we are disscussing, like prestolite, leese neville, etc. So we are good there, no?
The 2nd question is price. So if they jack up the price, is there a value added to their product or not? Also, what about the actual online price, how does it compare to say a non branded leese neville?
I don't think, but I may be wrong, but a standard auto alternator is not up to the task.
The ones for buses, and ambulances, and military seem like they would be.
But finding one that fits in my situation, mating it to a perkins
4-108, is difficult. One thing nice about balmar is they are easy to find the product you need.
One question about alternators that I have.....
If you get a oversized alternator, it still will only give the power the batteries acceptance rate will take, right?
But what about the hot rate vrs the cold rate. After a short time, those puppies get hot. And the output goes down. So wouldn't it be better to size it to the hot rate and not the cold rate?
while drawing from the batteries....
If your pulling a large load say running your fridge and freezer compressor
, your vhf
, making water
with a 12 volt unit like a spectra, fans and lights on, how much more amps can you expect out of a alternator that is say 120 amps and charging
a 800 amp house bank that is at say 75%. Usually the alternator will ramp
down as it gets closer to 80% on wet cell batteries at least, ( i have TPPL oddessey which can take a much higher charge rate over wet cells) But if you are pulling a fair load, what happens then ? Never tested it before, and now the engine
is out and the wires gone... will be a while to check it out....
