Alternator suggestions

[wildturkeypete]

Greetings All,

My alternator died on me last night and need to replace it in the driveway this weekend.

Anyone have advice on brands or companies to purchase from?

1997 F250 7.3l diesel.

Thanks!

DC Power is also another company.

These big amp alternators are a little pricey but it'll be the last one you will need to buy.

Thank you!

It appears that I need to get the Large Case alternator but I am not sure what AMP I should be get. 140, 160, 200, 250, etc?

I will be using the truck to tow a fifth wheel but will not be getting a winch or anything too heavy on the electrical. I will be converting to veggie oil but that shouldn't put too much of a draw on the batteries.

I want to make sure that I have enough power without over doing it.

If you got the $$ get the 250 amp.

One can only have 140 but if you end up needing 210 you will burn it up and get to buy one more alternator.

The auto supply store that I can get a good discount at only has 130 amp but they're going to see if they can do better.

I didn't even see 130 amp listed on the first link provided here:

3G Series Heavy Duty Bridge Rectifier High Output Alternator

Also.. Is there any chance if I get the 250 amp it will be TOO much power? I read before that too much power could be just as bad.

No. They're only producing the amps in response to the demand but you MUST upgrade your cables. Put on heavy gauge cables and file off any rust before putting the ground wire on.

I use a lifetime warranty from AutoZone.

That's what a buddy does and in the past six years he's had four warranty replacements, but he has enough lighting to land a 747.

It is possible. Batteries have a maximum charge rate dependent on size and type but even the 250 isn't going to put you at that limit with a pair of group 65's.

I put a 215 amp ambulance alt in my truck. I have 5 optimas, 10k inverter, 2 electric fuel pumps, 1 electric coolant pump, a few extra gauges and led lights, along with an aftermarket radio.

My headlights never dim, and my gauge needle is always happy.

Pictures and details are in my sig link.

I upgraded to a 2/0 welding cable for the charge wire and added a 250amp fuse.
