Inverter control panel isnt working

Welp one batt wont charge and the other says its complete but only showing 9 volts. Next step tomorrow is to pull them out and get them tested. Now onward to 12 oz curls

Those old Hearts have big transfer relays in them that can stick when they get old. The (temporary) solution in that situation is a solid flat palm smack on the side of the case. I got that from the tech who subsequently replaced the relays in my first Heart 25. My 2nd Heart Freedom had the relays stick somewhere on the BC coast & I thought "Oh boy, here we go again" but I gave it a smack, it started working again and we sold it working with the boat about 18 months later. Bottom line - if you've got a Heart and it won't go from pass through/charge to invert or vice versa, give it a good whack. What have you got to lose?

You are right. Im gonna get the batts checked and if they are good i will give the inverter a good slap. I have a feeling the house batts are too far gone sadly.

Update: took batts to O'reillys in hopes they can charge them. Turns out these batts were bought in 2011 so their life may be up. Will know shortly i guess depending on what the charge result is.

Im actually more worried about the inverter not working but everything points to it shutting down for safety reasons bc of low volts but im just not sure yet.

Some inverters can be very finicky about batteries. I have seen inverters that would not charge even with bringing the voltage up by another means, but they work fine once bad batteries are replaced.

Update: turns out the batts are dead. I ordered 2 replacements and will arrive thur. I took the gen batt out to test the inverter and sure enough i had 15 volts DC and my fridge and lights worked. Learned a lot this weekend and thanks for everyones comments.

That's a great old inverter you've got - don't ever let anyone tell you otherwise. Its got every bit as clean output as any of the fancy new so-called "pure" sine wave machines. Consider adding that control panel I linked - it will make the old girl tap dance.

I just yanked out a Heart Freedom that quit working. Those things are 20 years old now. I'm replacing it with a Magnum MS 2000 ME, pure sine.

there are 2 spade fuses under the cover..one clear one green 20 and 30 amp iirc...check them were i you...

the clear one goes most often.

like this ?

or this ?
