    This 2018/2019 Cascadia with a Thermoking Tripac (Evolution??) APU. Apu will not start and the control panel in the sleeper shows no sign of having electrical power. The APU outside on/off switch is verified on, oil is at proper level on APU oil dipstick.

    Symptom is that when driver presses on the sleeper's APU on/off selector switch to turn on APU nothing happens. No lights near that on/off switch illuminate. Lights in sleeper work normally. My guess is the APU's cable to truck batteries is not making good connection. Is there are a fuse, switch, or connector he could check? Truck has been parked for at least 2 months. Truck starts and runs normally.

    Try looking for the fuses on the driver side firewall under the steering shaft under the hood. There are two fuse boxes here. One for the SAM Chassis and the other is for the cut off switch. there should also be an Aux fuse box hanging above the batteries, but im sure the APU fuse should be in the SAM chassis.

    There is an inline fuse on the positive line going to the battery, more than likely blew that one. It's a big giant one, hard to miss.
