Thanks roscoe, you the guy, worked like a charm. Also nice all the fuses are easy to get to. Bad part is the printing is dark on black, hard to read, and my guess may not last very long
I don't have a diagram from your motor. I have one for the 5.8 (351) MPI and it also shows a jumper between the two points. Not saying yours is this way, but may be spliced inside the harness.
Measure voltage on each wire with key on and off to see if either or both switch
Don't know if Crownline has a breaker or a fuse
Look under the helm and follow the Red/Purple wire from the key switch to a breaker or inline fuse. Many cases its a 20 but can be a 15 amp
If there is a bad connection and it looses a connection, it can blow the ALT real quick. The Sense and Excite can be connected together so long as they read Bat voltage.
That said, the excite would need to be disconnected to keep from draining the Bat when its off
Assuming your talking about the 86 Conroy 4.3
Seeing anything above 15V usually means the ALT sense lead is not connected to see battery voltage, or the regulator is bad. AS dubs mentioned, could be a grounding issue.
Thanks guys, but have to take a hit
kbielat, most all boats place the kill switch on the purple wire after the key. The way yours works says the kill switch is on the red/purple feeding the switch.
Good luck
That's what doesn't make since. The wire rings out good but yet no power to the ALT
The kill switch should be tied into the purple. Basically the purple leaves the key switch and goes to the kill switch. From the kill switch it goes to the gauges and back to the motor as a purple. The...
Then your key switch is bad
Key ON and no power to the ALT, but wiring checks out.
Kill switch must be on the Red/Purple and not the Purple like all other boats
Either that or something was missed
Connect 10 pin back up.
Turn key ON and measure power at the key purple wire
You would get 0V on all pins but 6 on the motor side. Pin 6 on the motor feeds power to the key switch
Check continuity between pin 5 on the motor side to ALT and starter small post on outboard side. If it checks good, ring out pin 5 on the harness side to the key purple wire
Good, then the problem is on the motor and something is disconnected or broken. The purple wire comes from the key on pin 5 of the 10 pin connector.
From there it goes to the ALT, starter (small post on outboard side), coil and alarm. Pull the engine connector and check the pins
