My Trombetta selenoid on my 2003 Minnie Winnie 430V is no longer making contact between the coach and chassis batteries.
Solenoid Silver Contacts Continuous Duty Golf Cart 12V | eBay
I have found a very reasonable replacement with silver contacts on Ebay.
I have ordered one and will try it out.
Thought this might be an option for others with similar seleniod issues.
