My name is Joe Piper, I own Scenicrusier #743. I am trying to convert from 24V Positive ground system to a 12V negative ground system. The alternator shop tells me to mount a new alternator and bypass the old generator, then replace the starter with a 12V neg ground starter.

Question: what are we getting into with the lights and solenoid?

Thank you for your help in the past and now.

Joe

Can I ask the reason you are wanting to do this conversion?

Ditto on the question from GBL Rebel. I would assume that the reason the manufacturer used a 24 volt system was for a more heavy duty electrical system. You may run into problems with other parts of the system running on 12 volts.

My issue is the 12volt starter draws more amps then the 24volt. And I would like a bit of clarity as to a positive ground or positive ground on the generator field. However I am not familiar with the scenicrusier, I would imagine it is not to different from what I have worked on.

You might want to contact National Bus Trader (magazine):

They may have someone over there who has familiarity with Scenicruisers.
