Have a voltmeter? stop guessing, use the meter. same time and $$$$
starter? but what are the symptoms. ?????? no start sure. but
1: dead starter (not a sound)?
2: solenoid on starter click?
3: dead solenoid?
4: some times starts if i wiggle A/T shift lever? PRNDL bad.?
my guess, is the relay was good. all a long ?
if the old relay was burned to a crisp in inside (did you look) then
the starter can be shorted. they can in fact short.
we use to simple and cheap tools, a voltmeter and ammeter
The key switch energizes the relay.
the relay has a coil. if the coil goes to 12v, (meter across coil)
then the relay is energized. (cranking)
if that works we look at the relay output. (solenoids can short too)
use the volt meter.
if the voltage at battery sags below 10v. the battery is bad. or the starter is shorted.
we use an ammeter to see that short.
100- 200 amps (no engine stated but is covered in the FSM)
here is a voltage plot.
if you watch current it it goes to 500amps and the solenoid just bangs
the starter is shorted.
test 1: voltmeter to battery neg lug (black meter lead)
meter on 20vdc range (battery with meter there,,reads 12.6vdc.)
red lead to starter solenoid small wire, key line (sT) i call that.
I turn the key to ST position.
the solenoid ST pin (small) goes to what voltage. key held there.?
no wire pulled, this is a live test.
we do that first.
SOURCE: wont start, new battery, relay good, starter good.
Check the Starter Solenoid mounted near the battery.Check it out in the dark...have someone try to start it and see if it sparks at the solenoid.connections may be loose.Also check/wiggle wiring harness to starter.
SOURCE: starter keeps turning even when key is turned off
Curious, do you have an autostart installed? I had that happen that the Autostart shorted and just kept telling my starter to continue cranking
SOURCE: 07 grand cherokee 3.7 V6 gas engine. Vehicle wont start
I have the same issue. Did you get your problem solved?
