Ditto on that.
The unit has two (or 3) power leads
One is "MEMORY" Power. hooked to battery full time
One is "Accessory" only powered when ignition is in ACC position or a switch somewhere is in AUX position (optional swtich)
But if the power switch is lit, it has power
(3rd one is Dash Light by the way on the power leads).
I the switch lights up with key on and headlights off. Good chance it has power (only the one lead ACC, is needed to operate) And is dead.
