I have an M35A3 and had some fuel problems (see earlier posts if interested). The fuel in the tank is an orange color and no telling how long it has been there. A flashlight shows some material on the bottom of the tank and I'm thinking I need to empty the tank and clean it. I have seen...

To reply to Karl: The tank and lines have never been cleaned that I know of. The truck sat for quite some time before I aquired it. Have added fresh fuel since then but never really emptied the tank. Once started the truck seems to run fine but "greens up" in as little as one day. I have...

I have an M35A3. There is a brass check valve at the fuel tank which is giving me fits. If truck sits for any length of time, the brass check valve develops a green sticky coating which prevents the value from opening thereby starving the engine of fuel. I have to disconnect the fuel line and...

Finally got my "new" M35A3 running and home. Replaced the master and have power (two new batteries). Problem is the starter spins but does not engage. Do this 3-5 times and starter does engage and turns over in a very healthy manner. Does this indicate a bad solenoid or starter?

Thanks to all who responded to my question especially for the wiring diagram!!:-). Took a meter and checked the switch. 24 volts in and two of the three outputs on the accessory switch have power out, but the output powering gauges, buzzer, etc., is bad. Will have to order a new switch...

How do I check to see if the accessory switch is bad? Batteries are new and load test said okay. Everything else seems to power up just fine just the accessory switch that does nothing. Are there fuses or circuit breakers on this truck?

Just bot an M35A3. Went to start it to bring it home, flipped on the accessory switch and it buzzed for about a second and went quiet. No power to the gauges, air pressure horn, starter switch. Headlights, heater fan etc work so it is not a battery issue. Previously worked fine. Where can I...

I have acquired an M35A3. It came with two flat tires on the passenger side and a CTIS system whose controller I can't read but which obviously doesn't work. How do I trouble shoot the system? I have read enough to know that many will say disconnect the system, but I'ld like to try to see if...
