good morning my name is ***** ***** I will assist
first, nothing will work with 8.85 battery voltage. you need to charge it to 12.6 volts and then re test.
the alternator will work if it can once it has 12 volts to activate it.
lets start there and then re test
ok, with the battery being dead, the voltage will not build due to high amperage, if the alternator is working. it sounds like it is not but with a very low battery such as you have the testing is in accurate until your battery is up to voltage.
how are you making out
yes they are. at this point get the battery up to charge and then we will do testing. we will check with volt meter for charging and ripple on the diodes
ok, run the truck and see what the voltage is at battery
what is the voltage???
not good. needs to be 14 to 14.5 volts on dc
switch to ac and see if there is any voltage that will check the diodes.
please stop measuring diodes. not needed at all.
is the charge rate 13.8 volts dc???
all you need to do to check the diodes is measure ac voltage at the battery. it should be 0 volts. thats all the testing you need to do
please dont forget to rate me as it is the only way I get paid for my efforts
