Got a friend got 2008 signature and won’t start. Lights will come on and speedometer goes back forward and tach. Until you turn switch off. But I can go underneath the coach and start on starter. Nee...
Start with the batteries. Put a meter on them and see whether they're charged (at least 13VDC) Then check if he's been inside the rear run bay. There's two switches inside for a tech to start the coach without going all the way to the front cabin. Make sure it's switched for front and not rear. If it still won't start, turn the key to the ON position and try one of the switches in the rear run bay and see if it'll start......Dennis
