I was having same problem with my 2002 Windsor. After checking everything I put a volt meter on the battery maintainer center pole, it says negative , after checking, it turned out the wire that was connected was 12 volt positive. I removed that wire and ran a new wire to the ground bar. Working perfectly the last 2 years.

I believe that the gray wire is not connected to any sensor ( not used) When mine went into alarm I was on a trip so I unplugged the buzzer. The issue doing so is that you don't get an alarm when the transmission is in neutral and you don't have the brake pedal depressed or park brake set. That means the coach can move and you are not in the drivers seat. I would search the salvage yard for a new buzzer. I found one on the east coast but they wanted a $100.  good luck!!

Attached is a letter I received from Enertech. Hopefully this is clear thing up.

The testing was for the Enertech alarm buzzer. That is located above the accelerator pedal and has six wire disconnect plug. 

I have owned the 2002 Winsor for 18 years, I had the same problem for 6 years and finally replace the Enertech 4470-30 alarm buzzer. In-between times I used a switch on the power line in to kill the alarm. The buzzer is no longer available but found one at Colaw Salvage. Yes, I did replace the park brake switch that made no difference. To test the Enertech buzzer apply 12 volts on red lead and black wire to ground, then jump the white wire to red.  If the buzzer doesn't sound the buzzzer is bad.

I have done more checking and feel it's the Lambert LE415 problem, ordered a replacement AMP-L-START unit. Thanks all for the input.

I have owned my Windsor 17 years and both the house  and chassis batteries stayed fully charged when plug into shore power. In January I replace the chassis battery and now is not being charge. Where should I be looking for the problem?
