I have a 2005 Granite Ridge (Grayhawk) motorhome. It's new to me this year. The battery compartment showed signs of prior boil-over and outgassing. The battery (dated 2010) took about 1/2 gallon of water and was basically DOA.

I replaced the house battery, plugged the motorhome in, and measured charge voltage. We were at 13.6v constant, which is too high for long term charging and will eventually boil that battery out.

To exacerbate the issue on my motorhome, the push-to-disconnect was dead.

So I started looking into the charge controller (converter). On my motorhome, it's located under the rear bed next to the inverter (behind a cover). On others, it may be under the refrigerator. The model is IOTA DLS-45. This unit is a "dumb" charger - it's good that it can provide up to 45A of power even if the battery is disconnected, but it'll also fry batteries long term.

For Jayco motorhomes and trailers with the DLS-45, there is a $25 plug-in module that will convert this converter to a "smart" charger with a floating voltage option that part is IQ4 smart controller. It plugs in via an RJ-11 cord (plain old telephone cable). You can buy them on ebay or Amazon.

The one caveat is that some Jaycos came with an integrated charger and load center. This part is ILC-3045 and it was built for Jayco. It does not have the "smart" plug.... If you've got this charger, you're out of luck...

I got the IOTA DLS45/IQ4, which comes with the iq4 inside the unit. I am trying to use just ILC 3045 load center because the battery charger stopped working on my last camping trip. IOTA had something about taking the battery leads to the breaker then to DLS45. What I am trying to find out do connect the AC to the DLS45 and to load center? I am needing how wire it so it works without cooking DLS45 or burning down the camper.

I own a 2004 Greyhawk with the IOTA DLS-45. I bought and installed the IQ4 plug -in controller. It seems to be working. There is a green LED on the IQ4 that indicates which of the 4 charging modes is in operation. It cost me about $33 on Amazon. Well worth the cost.

Shortyr,

Go to the Iota website. If I remember correctly, there is contact info and wiring diagrams.

You are correct when you say that the constant output voltage of a "Dumb" charger is not good, it wither will never fully charge the battery, or it will overcharge, there is no happy medium.

IOTA with IQ-4 is a "Top Band" converter, Normally I speak of the Progressive Dynamics with Charge Wizard as the best, adding that there are others that are every bit as good.

Yup, IQ-4 is one of those others that are every bit as good.

Were you ever able to get any information on replacing the converter? I am in the same boat. I have the ILC-3045 load center with a bad converter. I have purchased the IOTA DLS-45 with the IQ4 built in. Looks like the existing AC connection is hard wired and the new converter has a plug...any help (Google so far has not been very helpful :().
