ok all that can be a result of low voltage. have you re charged the battery to full power and re try???

I got the truck started, the alt is putting out 14.5 volts when measured at the battery. the lights still on and no power to the windows

did you charge the battery ???

Customer reply replied 4 months ago
I charged the battery.

ok, when you jumped the truck, did you cross the cables?? I ask because if you did, it would blow some fuses.

Roy

No, I used the start function on the battery charger. I have checked all the fuses under the hood and the left end of the dash by the drivers door-all ok

ok, good. did you test them for power on both sides with a test light???

if they are. then the next thing is the body control module. from the fast start with a lot of voltage, it surged the bcm.

remove the negative cable and re attach after about 6 minutes.

This should reset the BCM? If this doesn't reset the BCM will it need to be replaced?

before assuming that, you need a scan tool that will read the bcm system and see if there are any fault codes stored. they are different than the engine codes.

Roy

I don't think my scanner will read BCM system unless the codes will show in the normal OBD port

they will but code readers do not always read codes other than the P codes which are engine related.

Ok If mine doesn't do have a brand you recommend that will

that would be a full blown scanner that will cost a couple thousand bucks. it would be cheaper to have a shop check it for you. most shops charge around 80 bucks.

It has to be in the truck to be scanned correct?

it has to be hooked up to the truck to be checked, yes, that is correct

OK, I will just try to disconnect the battery for a bit and hope for the best. if that doesn't work I will look at other options.

thank you
