Ok...On my last outing I seem to be having a problem with the main power lead coming into the RV. What is happening I was laying on the couch and watching TV (Small black and white TV) off my inverter which barely drawing 1.8 Amps and MoparMom would run a little water and the voltage would fall fast. Flip on a light volt would fall. Turn everything off and the volt meter shows low 12's... But just a few lights with drop in below 10 Volts in a short time. So I'm assuming there is still a weak connection between the batteries and the fuse panel since everything seems affected by it.

If you are dry camping then I would think of at least two areas to look at: loose or corroded connection; weak battery(s).If you are plugged into power then maybe a loose or corroded connection. I am not sure what operatring characteristics you would see if the inverter had a bad internal connecting or weak component.

It was a loose / poor connection. I found the junction area in a storage basement and re-twisted the line for the 12V and set the wire nut down tight. Then clean the light oxidation off the post and the terminals gave them a oil treatment like the truck. I want to replace the ring terminal and nip back a bit of the wire to freshen the connection but use soldier on ring terminals. Better than crimp ons.I did a quick test run and system worked better. Less voltage drop from a things. Like I fired up my 400w inverter plugged in a compact florescent light, VCR, and my portable 5" black and white TV. It was drawing 20 watts (1.6 Amps) and staying up at 12.2 to 12.3 with a full charge. As for operation of everything while plugged in... I can flip on every light in the house and the inverter to boot and still hold 13.5 to 13.6 with the converter running.The slide even moves a bit faster now while on battery compared to before...I know I know... I tell you guys all the time and this time I should of heeded my own warnings... :banghead:Yes I can still sit back and laugh about it...
