Our Perkins genny shut down due to over heating. We now know that the Murphy Switch protection system works, even after 36 years. After a good look at the generator system, which I really have not done in 4 years of ownership, I found some things that confuse me. There are some modifications that were done a long long time ago judginging by rust and debris. I know the previous owner well, and am sure that these mods were done before he bought the coach.
The 3/4 120 volt blower motor had blown fuse protection installed (inline) on the incoming hot and common wires about 6 inches from the motor. They are standard automotive 30 amp 30 volt ? Yes 30 volt rated fast acting blade fuses.
Motor was non op due to the pinching of the 120v lead on the motor frame. Perhaps that was why a prevoius owner had installed fuses on the motor?
The belt pully has been stressed and broken. Before removal I checked belt alignment and it was good, there was no side load.The photo makes it look as though it is not in alignment, but it is right on. I had noticed cracks in the pully a year ago.
There is no way to adust belt tension. The motor base holes are not slotted.
The base area of the cabinet has been cut out with a torch at some time in the past. Maybe to let the air horns mounted inside to be heard? The motor had a lot of road debris around it from the hole cut in the floor area Doesn't this stop the cooling process the same as leaving the cabinet door open ?
Can one of you Classic guys post pictures of your genny cabinet?
Any and all suggestions are appreciated.
