the new batteries have been on trickle charge for 3 years- unused. the tech said they were fine.

Progressive Dynamics makes several converters that are a direct replacement for your 7300 series. Here is a link to the 45 amp version.

The PD converters are much better than the Parallax converters, faster charging and easier on the batteries.

lights seem to cycle every minute or so.
parallax power convertor is what came with the MH series 7300.
the first 2 were changed when a loose connection on the lower right of the board, burnt the board.

Lights brightening and dimming may or may not be normal.. What is the cycle rate?

Here is why I ask.... My 3stage PLUS converter has, as suggested an additional feature (A Plus) that being an automatic equalization mode that is invoked for like fifteen minutes every 20 hours.. Lights get Brighter for 15 minutes.

In some cases a circuit breaker may be cycling, this usually is 3 minutes or less.

Other devices may be demanding power (When wife presses button on macerator toilet.. It dims the lights).

anon125,

Are you still out there :) ?

Your post sparked a lot of curiosity. A real teaser for digging. Could you offer the make of converters, the size, the size of your rig? Three converters in how many years.

Agree with others, classic dying converter symptoms.
The good news is this is your chance to upgrade!

I had same issue. The converter was bad in my unit. Just unhook battery leads and check output at converter
