So, the kit says older classics need the FET Bar removed to dig down to the fans.
Newer ones, have a farside access port for the replacement
Question is, what serial # defines Old vs New chassis ? any frontside visual clues ?
#CL11788 ( it's not on the internet, ever )
Good question.
But I have a feeling that SN ~11,000 is not new enough to have the newer rear fan opening.
It will be obvious though if you look at the back of it.
I'll find out what serials that started at.
for me, it would be a major operation to change the fans. so i added external computer fans. the reasoning is to use the internal fans as little as possible.
with the added advantage that all the electronics and caps keep cooler and should last longer too.

Great idea if that isn't too much trouble, AS.

it is not much trouble at all. in the midnite for the 12V system the internal fans still come on occasionally under full output.
as a matter of fact all my inverters have fans underneath too. the fans are on a timer, some on temperature sensors.
