Well im having the same issue and actually getting pretty hot from it not running. Its getting power just havent dug in deep to see where the ground is but i did see what im asuming are ground (s) running to each side. Im going to have to get a meter to do anything. Now would any one suggest if i removed the radiator fan to go with an electric one; would it be ok getting a larger then stock fan to have one electric fan replace the engine driven fan and condensor fan?
Yes, what you are seeing are grounds.
To simply check the ground on the fan, just take a meter and put one lead on the ground wire in the plug at the fan and the other lead to any good ground source, then see if you have continuity. If you do, then the fan is probably bad. If you don't, then the ground connection isn't good (either corroded/rusted, or you haven't got a good connection with one of your meter leads).
I'd suggest testing the stock fan clutch first, to make sure it is working correctly. A properly functioning engine driven fan and clean coolant system should cool the engine fine.
If you are having problems with it overheating only when you are running the AC, then once you get the electric fan to working, it should keep eveything cool.
I would keep both fans.
