Question about Iota DLS-45-IQ4 Battery Charger Converter

Open Question

Last year my DLS 45 converter would not recharge the on board 12v battery. I could not get service at Camper World shop. An independent trailer repair place could not fix it either. Per their suggestion, I used an external battery charger for the rest of my trip. Upon returning home, I ordered a replacement DLS 45 Power Converter, and switched out the units. This unit does not recharge the coach battery either. When charged, the battery and RV systems work normally. It is fully discharged within a day or so, with a couple of 12v trailer lights burning. So in summary, the output circuit works, the recharge/battery maintain circuit is not working. Any suggestions? PS: the converter is still under warranty.

When I unplug the power from the trailer, I lose all power. I have brand new batteries. someone told me it may be an inverter. Where would I find this or check it?

You have new charged batteries? Then my guess you have a 12V cut off switch somewhere like I have in my camper, or a fuse blown in your panel. If you are getting 12V accessories working when you are plugged in, it is not the inverter.

You might unhook the battery and with the camper plugged in to shore power the 12v lights should work. If not check the breaker that goes to the inverter. If that is not tripped then check the power output at the converter. I would expect the inverter is shot. I replaced the one on my Jaco two years ago with (Progressive Dynamics 60 Amp Power Converter with Charge Wizard and the remote pendant)

When you open these things up you with likely see a 12v power supply, a circuit board and a battery. If it was working properly the last time you used it then it is likely the battery. You should be able to pick up the battery online. There should be a stamp on it to tell you what you need. It wouldn't hurt to test the power supply independently to see if it is supplying the proper voltage since you have the case open.

Just hooked up me camper and when I turn on the truck lights the trailer brakes lock up. Turn off the lights and they are fine. Please help! Thanks, Bryan

The plug on the camper doesn't match the wiring on your truck, when youturn the lights on it is sending 12v to the brakes.

This is the way your trailer plug should be wired if your truck is wired standard.

I can't locate the 12 volt converter in my camper

They hide them under seats, in closets, in side storage compartments.

The unit is often a shoebox sized box with a power cable in and cables to the battery out. OFTEN the fuses are located centurally for the whole trailer.

While properly charging, you should see about 13.5 to 14 volts across the battery.

Sounds like a fuel problem. Change the filter and have the fuel pressure checked. A fuel problem can cause an O2 code.

I have an early 90's Starcraft pop up camper. I just went to hook it up to the van and the travel lights (running, brakes, directionals) don't work at all. All lights worked when the camper was stored last...

When you say that you have power up to the camper, do you mean power through the pigtail/wiring harness with the tow vehicle connected?

The trailer harness wiring is the only way to power these exterior camper lights, i.e., through your vehicle. There are no fuses within the trailer for the exterior lights. These lights are only fused from the tow vehicle's fuse box. So either the connections in the trailer harness are open, or they're open at the tow vehicle connection.

Do the turn signals work on the tow vehicle? If yes, then the only other thing to check is the turn signal flasher in your tow vehicle. A heavy duty flasher is recommended.

From the trailer, yellow, white, brown, red, green, is connected to your vehicle backup, ground (frame), right turn signal, left turn signal, running lights, respectively.

The trailer's blue wire is for an electric brake connection to your vehicle.

The trailer's small black wire should connect to the vehicle's hot, 12V lead for the interior lights. The large black wire at the trailer hitch is for charging an RV battery on your trailer, if it's supplied with one. Of all of these wires, only the large, 12 gauge, black wire goes to the 25 amp converter, which is fused, for the inside lights of the camper.

I hope this helps.
