what did I do?

[gonesleddin]

ok lets start this by saying I already knew my starter selenoid was bad....turned the key on and jumped across the selenoid, sled ran no troubles, brought it home from storage turned the key on nothing....checked all fuses and they are ok, replaced all relays except starter selenoid (it seems that no dealer can figure out what part # the selenoid is) and I still have no power to the dash...yes the kill switch is up just wondering if I f$%# the computer, any suggestions????
thanks

silly question for you. is the battery dead?

 

[gonesleddin]

nope it is new too....if i jump across the selonoid it turns over

main fuse in front of the starter relay?

I listed the part number for the solenoid in the "Nytro Fault Codes and Relay Location Diagram" sticky. the second diagram is the relay location and parts numbers.

nope I put a meter across the relay, and its good, thanks for the info on the selenoid, just wondering there is a plug in diode that comes off the seenoid coil, dont know if that would affect the rest of the circuit if that is shot

It sounds like you lost power to the ignition circuit. The sequence to power the ignition is battery, main fuse, ignition fuse, key switch. With the key switch in the on position the power feed splits to the ignition system and the power distribution circuit (lights). With the key on check for voltage at the headlight or signal fuse to see if the power distribution relay is being powered and check for power at the starter relay for the ignition feed (red/white wire in the connector). I had a problem with corrosion in the plug coming of the key switch when I took mine out of storage. The diodes could cause a problem but I've never heard of anyone having problems with them. One of the diodes is a zener which is a voltage regulating diode. They normal fail as a short circuit however if both short circuit I would think the ignition fuse would blow when trying to crank the engine. If they fail as an open circuit the stored energy in the starter relay could back feed and damage the ECU.

The starter relay is energized in the crank position by a ground signal from the key switch. This ground is also sent to the ECU. I'm not sure what goes on in the ECU with this signal but when jumping across the starter solenoid the key probably should be in the crank position.

thanks grizztracks....all good now, I just wiggled the connector off the key switch, fired right up, the selenoid stuck once but engaged the second time, just ordered 2 new keep one as a spare, pouring rain right now so when the weather get a bit better I will pul the connector apart and clean up the contacts, I can see how moisture can get in there the wire end is exposed thinking i will seal that up...thanks again for the input
