IOTA DLS45 Charger issue

[mbrund]

I have two of the 45's in my coach from the factory and I see an odd
issue with them. When I get to a site after having driving for a
long time, and I plug the coach in, the chargers will cause the amp
meter to rock back and forth from charge to discharge, and the DC
lights have flash at the same rate.

If I go to the battery compartment I can hear a clicking noise in
both chargers, at the same rate as the lights flashing. If I look
at the cooling fans they appear to be kind of rocking to the rate of
the clicking noise (not spinning, just kind of moving like 1/50th or
so of a rotation per click which occurs about every .5 to 1
second). I replaced both fans thinking they where the issue, but
the charger and fans still do the same thing.

Neither has an IQ4 smart controller installed. I can disconnect
either from AC power and the other continues, or just plug one in
and it starts doing this. Not sure, but they seem to not do this if
I let them cool off for 8 or 10 hours after making a drive where
they get heated up by the engine and road conditions.

I will contact the manufacture in the next couple days to discuss,
just wanted to know if anyone has ever seen this with this charger?
