Lets get clear.
1. You state the IGN system. You mean it does NOT short until you turn the key all the way to engage the starter?
2. The Ign controlled COACH systems including Dash Area(Back up and so on) all work even when the other fuse blows? Doug


The key switch excites both the ACC and the IGN at the same time. when the key is turned to either position, then you turn to IGN and continued to turn to crank.

the fuse blows as soon as either position is reached.

this is why I say there are two discrepancies.


Yes and No. When you turn to IGN(NOT the spring loaded Starter position) it activates Both ACC side and Ign side circuits. BUT, when just going to ACC, that position activates fewer circuits than the IGN side, BUT, will still activate the 1 circuit that blows the fuse. ONE problem, for both sides. Once you find and fix the short, BOTH sides will work and not blow the fuse. Lets wait until you do your ECU testing. So, you refuse to doublecheck the batteries? Doug

. Exactly what fuse is blowing?
Jerry
And what size is the fuse? How many amps?


It is labeled " 15 Key SW' and it is a 15 amp

It is in the #1 junction box.

If you have the schematic that shows which items are powered via that fuse
Remove fuse check continuity to ground from that feed to ground,
Now the slow part, one by one disconnect each item until you find the one that makes your continuity short disappear
I suspect that something has failed, something that would automatically have power, not something you are going to manually b operate a switch for,
Unless you have had a rodent chewing on wires, that should be visible unless it chewed a random spot In harness somewhere, creating a short between that hot feed and the ground lead for something else
How long as it been parked
