[RE-wrenches] Faulty PM-60 circuit board

[Ray Walters]

Today's controllers are so much better both in terms of battery 
management, and power efficiency, that I replace the old Pulse stuff 
even if they're not dead. I usually keep the PC250 as a DC load center, 
and pop a new controller off the top. This is often a good time to add a 
few modules to the array, and rewire the existing array to higher 
voltage. This allows the existing home run wiring to be reused, even 
with the additional modules. I've found that if the original array 
wiring was good, that it takes very little work to jump up the voltage. 
Definitely don't need to redo every connection.
People are used to upgrading to better electronics: who still uses their 
computer, modem, or cell phone from 10 years ago?
Today's controllers will pay for themselves in extended battery life alone.
