How to fix intermittent loss of electrical accessories.?

Clean the terminal and the cable end. Then tighten it up good. Use some anti corrosion stuff on it when you are done.

Thanks F_O_R , But this goes way beyond dirty cables at the battery. However it could be something as simple as that. But it sounds like a circuit breaker reset. It works for a minute and then everything quits again. The terminals are brand new. Thank you for answering.

If you replaced the terminal (cable end) you may not have achieved a proper connection. Check the accessory hot wire!
