[RE-wrenches] Intermittent charge 4024

[Mac Lewis]

Hello Wrenches,

I recently assessed a 22 year old Trace 4024.  During bulk charge mode, I
noticed that the charge would go from about 18A down to 5-6A every 15-20
seconds, and then repeat the cycle.  I observed this for about 5 minutes
relatively consistently  I also noticed the body of the 4024 was very hot,
and I couldn't feel a fan moving air through it.

I put a fan on it and blew air over the body of the inverter, trying to
direct it through the machine.  While I did that, I never observed it drop
out again over about 5 minutes, so I'm assuming that there is an internal
cooling fan that has gone out.

It's been quite a while since I opened one of these up.  Does anyone know
what's involved in replacing a cooling fan on one of these?  Is it worth it
on a 22 year old inverter?

Thanks in advance
