I've had my P30 for 8-years. I love its ability to truck and provide a 'home-away-from-home'. I've had my share of trouble understanding the differences between gas and diesel and the differences between carburetion and fuel injection. Now I have a problem which has me totally confused. My starter began to stick and just 'click' when keyed to 'start'. If I repeatedly turned the key to start it would eventually kick-in and turn-over. I removed the starter, took it apart, cleaned it and emery-papered the commutator bars. Its brushes and spring pressure were all good. I replaced it but the same condition still existed. I assumed the problem was the solenoid. I bought a new one and installed it. On its first attempt to start the vehicle, the starter would not stop when I turned the key back to 'on', or back to 'off'. I returned the solenoid as defective. Even though the seller insisted the fault was not the solenoid, he replaced it. The same condition still existed. I took the starter out again and benched it. It works fine. I re-installed it...same thing. I meter-tested the switch; it's okay. I've now had the solenoid seller and two others tell me this is normal, yet in 8-years I've never had this happen no matter how low the batteries were. Am I now in the Twilight Zone?
