While working on my class 530C firetruck today, I noticed that it had a short
circuit. I hope someone on the list can help me with this. Ideally someone
out there has a wiring schematic. Please note, I have all the books on the
chassis (M45A2), the problem I have is in the body wiring, and despite
repeated efforts I have been unable to locate an operators manual for this
vehicle. I have tried this list, eBay, NTIS, Portrayal, and Aberdeen.
In the event that no one out there has a schematic either, hopefully someone
will have first hand knowledge of this....
On the inside of the cab on the firewall there are 4 circuit breakers
mounted. If you are in the drivers seat, what does the third circuit breaker
from the left control? It has gone up in flames on my truck. Scrapping had
begun on my truck when I bought it, and many of the wires have been cut. I do
not know if this damage occurred before or after the scrapping began. All
the electrical system that are part of the M45A2 chassis have been repaired
and function properly. The roof beacon works, as does the siren (when using
the steering column control). All the lights at the pump operators station
work, as does the heater.
None of the spotlights work. The electric hose reels are not installed, so of
course they do not work. The light on the passenger side control panel does
not work (it appears the toggle switch is bad). The lights under the hood do
not work. The auxiliary generator is missing (anybody looking to get rid of
one???). The passenger floor control for the siren does not work.
Ideas anyone???Or schematic?
Thanks,
David Doyle
