no power to 06 Bus ignition

[plweljr]

Hello, I have no power to the ignition on my bus, batteries are fine. This came about when I replaced a mini spade fuse/breaker, I think, from freightliner it was the 30 amp fuse that is about an inch and a quarter long. This fuse is marked marker lights. When I put the new one in from freightliner it blew the power to the ignition. I have checked all the fuses that I can find and all seem to be fine but still no power? Does anyone have an idea where else I can check? Thank you. Paul

You may have a couple of large circuit breakers in the bay with the chassis batteries or the one behind it. Either those or large 300 amp fuses. The breakers and fuses would look similar to the photos below.

I have checked the 300 amp breaker, I'll have to check for main chassis breaker, don't recall seeing that. would make sense cause I don't have headlights or turn lights, nothing from the 12v side. I have electrical power, as in house lights, just nothing to do with ignition.

I don't know where the ignition fuse is located. However, though I have never actually checked, there is supposed to be another fuse panel in the dash behind the computer. Unscrew the faceplate for the computer, lift it out, and look.

Not really sure where computer is located. Is it on the firewall down by left foot?

Looking through the owner's manual, it appears the computer was an option. You might have two drawers below the center cup holders instead. Look behind them for additional fuses. They're the drawers pictured on p. 5-2 in your owner's manual. I have never looked, but Tiffin Service tells me they're there.

If you do have a computer, it's in the dashboard below the monitor that doubles as a rear view/side view camera monitor and runs Windows XP, right under the center cup holders. It runs incredibly outdated navigation software, too (smile) and occupies the space taken up by the upper drawer. (Now that I realize this I might look for a drawer. The computer is a waste of space.)

Yes, I have checked all fuses under the two drawers in the console. I have checked the resettable circuit breakers in the battery compartment, although I do not see a way of resetting them. I have checked voltage on both sides of them and they have voltage on both sides. Guess I'm gonna have to keep looking for more fuses when I get home this evening but have about ran out of places to look

Not sure what CBs you saw in the battery compartment. The CBs in the compartment behind the battery compartment (behind the plexiglass near the inverter) are self-resetting.

There are more fuses and/or CBs in the upper part of the compartment where the power cord goes, and IIRC there are more in the forwardmost compartment on the driver's side. You wouldn't want to have them all in one place, after all. ;-)

Possibly the best thing at this point is to beg, borrow, steal, or purchase a line tracer. Hook the transmitter to the ignition switch and use the receiver to see where the line goes.

I had this same problem, it was a bad connector under the dash to the ignition switch.

Thanks I'll check it out

Thanks to everyone that offered advice on this. The problem was actually a bad connection in the black plastic box behind the tag axle that has a starter relay inside. Why you have to hunt 4 different places when you have an electrical problem in these things is RIDICULOUS!!
