DC Power Alternator died

i just had my 190amp DC Power Alternator just died. It was about 4 yrs old. I ordered a new Bosh AL7606 I know it's 140amp but it was half the price and in stock on amazon also lifetime warranty. I'm thinking of moving the pulley from the DC Power to the Bosh. Any thoughts? I went to the DCPower website but they were sold out and twice the price. I might just get the DC Revuilt as a spare?

I own and have tested the Bosch. It's a good unit and I often recommend it.

It comes with a stock size pulley. If your DC has a 58mm pulley then I would switch them on arrival. If not, I would get a 58mm pulley off eBay as they can be had for around $12 shipped.

From what I've read DC always shows out of stock, but I think you made a better deal.

I know the DCPower has a small pulley but I don't know what size it is. The stock size was a good bit bigger

glad its its a good unit

Stock is 69mm 8 groove, overdrive normally is 58mm 8 groove.

DC gets part of it rep due to the pulley they install.

AFAIK they don't do direct consumer sales anymore. A vendor like FICMrepair.com can get them, and Ed usually stocks a bunch.

Instead of rebuilding the DC, you could probably pick up an LN230 for not too much more.

We stock the DC Power and Leece Neville lines, but also rep for the OEM, Mechman, Mean Green, and Singer lines, which can usually ship same day regardless. Thanks for the tag!!

Is the LN230 better? I know it has more amps but I'm looking for durable as we haul a rv all over the place with family. Looks like it has 1yr vs lifetime warranty on bosh.

similar situation here Ed, do you have a top three list or something?

edit: thanks for that fast turn around fixing my faulty brake controller!

Lifetime warranty on the alternator is nice and all, but that doesn't get around the fact that 140A just isn't big enough to run everything. I'd rather spend the money on the alternator to keep everything downstream fed correctly.

Jack would be the authority on if an alternator is built to a higher amperage spec than another, than that higher unit it should be more heat tolerant since it's built to sustain a higher output? I've wondered if the 110A units die sometimes because they get heated up worse by being pushed too hard almost constantly. But that's unfounded speculation.

So far in my experience they both are durable, but the L-N was designed for commercial use and I've been impressed with it.

The last two weeks I've been redoing my long lost vid on alternators, my 6th+ attempt at this so I've got data in front of me. But here is the recent thread as to not reinvent the wheel:

I just test stuff......

Was never a fan of DC, If want the juice LN is the way to go. Bosch is the stock alternative with a small pulley.

Imo the 140 is fine and covers the load. The high output units just don't hold up I've found.

I had a Tenney, it burned up. Then I had excessive amperage build it and he said that Tenney used crappy parts and that's why it burned up. The excessive amperage one did the same thing shortly after. He wouldn't warranty it. The Napa one is just fine now. I think it's a 140
