Good advice above, many Mahalos....
This truck celebrates it's 20th year on the road this year. The motor has been no problem at all, but it has burnt through several th400 trannies, the current version is holding up pretty well, running Mickey Thompson Sportsman S/R Radial 31X18R15LTs on a 9" I narrowed to fit after modifying the frame extensively, it will break the tires loose whenever I want. I ran a pretty stock alternator with no problems for many years, but the last two "stock" alternators from Napa sucked bad....
Funny, I didn't know this, Napa sells me an alternator, supposed to be like the old stock ones I ran for years, and I can't get voltage !!!
So I take it back, they give me another one, samo samo....
Can't get the daggon thing up to even 12 volts, heck, with the hi beam lights on, can't get it to 11 volts....
So I take it back, it's faulty, I want a refund, "oh, we don't do refunds on these, I can give you another one to try, but we don't do refunds....."
"I just tested it, I didn't drive it around, just testing, and it failed my tests, it doesn't produce the stated voltage...."
" I want a full refund, as I am going to look elsewhere for an alternator, one that works...."
"No, we consider it used once it walks out of the store, no refunds...."
So that battle with my local Napa just started, and I'm again running the 140 amp with 13+ volts showing on the voltmeter....
And no screeching belts...
Yet....
Aloha all...
