1995 American Eagle/Spartan Chassis/Dash Blower

[jDavid]

What is the typical electrical load of the Spartan MM Dash blower. On three different trips, the coach engine had shut down (everything turned off). I finally figured out what caused the shut down. The dash HVAC blower every now and then will load the electrical system down to 8-10 VDC which will cause the fuel control relay to open and shut the engine down. The engine will start back up with no problems noted. All of this is very illogical. The blower puts out enough air, it does not make any loud noise, it just every now and then draws excessive amounts of current. You can vary the speed back and forth with no apparent effect. The scary thing about this that on one trip we where coming down a mount road and it was raining, I was pulling a toad and the thing shut down. It kind of shook me up! Anyway has anyone has a simular problem?
