That is great John. Learn by trial and error...common sense. I too am not keen on 440/480 type work. I can work 220 volts and such but 440 you have to be very careful.
Even circuit board work is a valuable commodity today.
Before paying some 500 dollars plus for a new Anti Brake Module...on my van I am going to try to remove it and closely examine the circuit board for cracks and bad grounds. It works fine when it is cool/cold..but when it heats up the ABS/Brake light come on. I think it is a crack in the circuit board..heat expansion. If Not I will make the expenditure for a new one but figure H have little to lose by exploring it myself.
Have a 1200 watt inverter here...never hooked one up but I will learn.
