cranking amps...

any idea how many amps are on the switch to solenoid wire when cranking?

 

Are you referring to the FORD fender well solenoid??

I dunno but I can measure one, I'd guess four or five amps.

 

yes and thank you

yes...and thank you...

 

At 12v, 3A. Pulls in at approx 8.5v, drops out at just under 3V.

So a chattering relay means under starter load, battery voltage is falling to less than three volts.
(not that you asked, I like learnin' stuff)

 

thanks...
