I'm Awesome
Hi all,
I just joined the forum and have been reading numerous postings for info on all things GMT400. I recently purchased an ex-ambulance so wiring has been a crazy mess. Not just the normal extras like UHF and horns, Im talking extra lighting on its own flashing system with the horn, dual battery setup, radiator coolant motor to run after engine stops, central locking, adjustable shocks from inside the cab, switches galore, 240v..anyway you get the idea. I'll attach a photo tomorrow of some of the wiring I've removed, I'll need a skip bin its pretty funny.
That aside, I'm still having some issues which I haven't been able to find on the various forums and postings.
Actually there are a few. But the main one Im hoping to get an answer for is whether all wires on the ignition switch should read battery voltage when ignition is switched to run?
I'm having issues like no tacho, speedo, temp and fuel but backlights work and most other lights seem okay. I haven't got a code reader and cant drive it at the moment to test if the trans is playing up, but it goes into drive, reverse and gear indicator lights up. I'm leaning toward the ignition switch being the culprit, but who knows. Any help appreciated.
