INSTALLED THE M105612 CROSSED FROM DELCO 10479215,GOT IT FROM OUR LOCAL SUPPLIER,NO TAGS AS USUALLY ARE ON TERMINALS NOTHING ELSE IN THE BOX,INSTALLED AFTER SYSTEM CHECK IE VOLTAGE & CONTINUITY ETC.STARTER SPINS,BUT WON'T ENGAGE FLYWHEEL,THIS IS A 2006 FRGHT.M2 WITH THE 3126 CAT ANY SUGESTIONS?
We have a 3525JC 12volt alternator with an IGN terminal, fed by a key on ignition wire with a diode. This terminal also has a jumper to the main positive output terminal. With the ignition shut off, there is still 9.3 volts at the IGN terminal. I don't understand the need for the jumper.
1. Is it normal to have residual voltage at this terminal with everything shut off?
2. Does this alternator normally have a sense terminal? If not is it possible to add one, for use with a battery isolator?
Thanks for your help.
