On Battery, lights ok; slide, awning & jack kill battery

I have searched here but couldn't find an exact situation that I have.

2014 Keystone Bullet Premier
  • did a reverse polarity by accident!
  • Polarity fuses didn't burn out
  • 3v Refrigerator Controller Fuse burned out and replaced. (Frig Works)
  • replaced battery
  • replaced Power Converter
  • replaced Polarity Fuses
  • cleaned battery terminals


On shore power everything is good.
On Tow Vehicle Power everything is good.
On Battery, lights come on dim, then if I switch them on and off they come up bright.
Battery 2/3 on monitor.
On Battery, try slide, 'kills' battery. Same with Jack & Awning.
Not sure what to try next.

Can't locate any 'hidden' fuses. Are there any?
All 15 AMP fuses good.

Take battery back and get a more powerful one?

Battery is a:
Duralast is a 24MD-DL
Cranking Amps 1000 with 115 Reserve Capacity.

Thanks,

JERE

  • Sounds to me like the battery is shot. Lights are a small load. By trying the jacks and slide you are putting a bigger amperage draw on the battery and it can't supply what is needed to run those loads.

  • Jack and slide motors pull a lot more 12v power than lights...
    Sounds like a weak battery either not fully charged or is not being charged by the converter...is the converter supplying a charge to the batts? This is easy to check with a multi-meter.

    There are a couple of blade fuses on a converter (mine has 3).

    Good luck with you search of the infamous electric gremlin...
