Have a redarc BCDC 2420 (20A -24volt to 24volt Charger) this has been the most disappointing product I have ever fitted, its been changed twice & only ever works for a few days then stops working, Its been back to the Auto elect 5 times, yet I have a BCDC1240 fitted as
well, working 24v to 12v & is no problem & works fine like all the other redarc products I have fitted.
Has any body else had problems with this new model charger?
It is fitted to an 2014 Isuzu NPS 300 crew cab with a warrior conversion

Duck,
I have the exact same unit charging 2 x 110ah AGM batteries.
After it was installed I had endless trouble. The unit not charging, the batteries going flat etc.
My comments;
1) when the unit was installed it was done poorly. I had huge amounts of trouble. I took it back to the supplyer / installer 3 times but they could not fix it.
They too replaced the unit, assuming the unit was faulty.
2) I contacted Redarc directly & the local rep (Stuart Peddle) came & inspected my installation.
3) Stuart found several things incorrect with regard to the installation. The 2 major things were (a) the majority of connections were loose, (b) the unit had a very poor earth.
After all connections were cleaned tightened or replaced, and the earth connection was sorted, the unit has worked faultlessly.
Conclusion;
Check EVERY connection. All wires, fuses, everything. Make sure they are all tightl, clean & free of corrossion.
Check the Earth connection. I suggest that you remove the paint back to bare metal at the Earth point & then recoat with something after installing the Earth strap.
I did all of the above & have had absolutely no trouble since.
Others have also noted that the Redarc is very sensitive to poor installation....
Hope this helps
Cheers, Bryan
