> No more ping from the motor now that the amps are up.What went wrong?
Unlike a carb. vehicle, EFI needs at least 35+ amps to run. I know my little Bronco II drew about 35 amps just idling when I put it on a meter. If you take a EFI vehicle on the road with a dead alt. you usually can't make it to 40 mph without sputtering and dying because of the draw.
> Dose my Napa need a new tester.Or did they just go out back and smoke a cig
I would go with #2. Many people have the attitude "its new and in the box so it can't be bad" and assume you are stupid and wasting their time. I have had rebuilts that are bad right out of the box and if I have to drive any distance back to the car I have it tested (alt and starters) in the store while I watch to make sure it is done right. Kind of funny when two "new" ones fail in a row inside the store.
In the fwiw department, I never had a Ford RMP bad out of the box and I sold hundreds of those while working a Ford parts department.
A lot of counter help have no clue how to test it, so they hide somewhere come back and say its good.
re:relays
In the FWIW department, besides being damaged from bouncing around, if they are not mounted so the prongs are facing down, they can fill with water or condensation (even if potted) and damage the coil/magnet inside and prevent it from switching the 12V through.
In the FWIW department, it is normal on newer Fords (and others) for the alt, starter, fuel pump, and relays to go bad if they sit not running for any length of time. Then you always have rodents that like to make nests and chew wires to make it worse.
You are on the road and running so its all good

Yes,chipmonks are real bad to.They nested in my Zero turn lawn mower last winter and chewed off all the rubber around most of my wires.My friend had a real big rabbit and it got loose then went next door to the next house over and ate every wire it could find,It chewed all the wires under a car parked in the drive way.Then all the wires on the side of the house like telephone and cable tv wires.It was to funny.I think my friend ended up paying like $3,000.00 to fix every thing that the rabbit chewed.Ive seen a mouse run off with a whole pack of cigs.Crazy little buggers.
