OK - so I've traced my electrical problems down to as far a my knowledge will let me go. Need your help to go further. Here is what I know after following JeepHammer's directions.....
Got a multimeter and set it to DC Volts
Battery showed 12.6V
Doesn't matter what the battery voltage is, but it's good to have a baseline when you are checking to see what the 'Drain' is...
DISCONNECTED the NEGATIVE battery cable from the battery.
DISCONNECTED the 2-prong plug from the alternator.
Connected the multimeter leads between the NEGATIVE BATTERY CABLE & THE NEGATIVE BATTERY POST.
At this time, the multimeter is showing a 11.96V drain!
What do you mean "This Time"?
You didn't do a drain check before, so why should a drain voltage of 11.96v be a surprise....
You knew there was a drain, you knew it was a pretty healthy one...
Why the surprise?
Started taking the wires loose from the starter solenoid.
1) Removed dedicated light switch - still 11.96V
2) Removed "fuse box wire" - meter dropped to 0V.
That means the 'Drain' is on the fuse box wire circuit.
That makes things easy!
So, this shows the drainage in the fuse block.
Correct! You are on a roll!
Reconnected the "fuse wire" to the solenoid and connected two long wires to the meter and placed meter in the cab. Still showing 11.96 V drainage.
Exactly what you were supposed to do!
Started pulling fuses. Only the hazard fuse when pulled, 11.96 voltage drops to 0V. All other fuses showed no change in the voltage, only the hazard fuse. So, the drainage is in the hazards circuit.
Funny though, the hazards lights work fine.
HAZARD has more than one thing on that line...
So.....now that I know it's in the hazard circuit(s), how do I find this 11.96V drain?
You get a wiring diagram and look to see what else is on that line,
You check the hazard switch for current when it's 'Off' to see if rust or corrosion has made a connection in the switch,
You look to see if a Dip Stick PO attached anything to the hazard wiring.
Since it's full time 'Hot' that's a REAL possibility and something I've seen before!
Do I start checking continuity on each wire, check for a loose ground, cut wire, etc? Where do I go from here? Question, if checking continuity, a zero (0) reading means the wire is good, anything else means there is a knick, short or some other problem with the wire, correct?
I'm going to pretend I didn't read that!
I've gotten this far on JeepHammer's directions, I'm just at a dead end (pun intended) and don't won't to ruin a battery.
Also, don't know if it is related or not, but when the emergency brake is applied, and the ignition is off, the brake light on the speedo won't go off. It is staying on. If the emergency brake isn't applied, the light doesn't come on. Just curious that the e-brake light won't go off even though the ignition switch is off. And yes, I've made sure the e-brake light isn't draining the battery.
It may be related, leaking switch or a switch that is making partial contact would cause the problem you described.
Let me look at the book to see what else is connected to that circuit...
