engine dying due to electric fan

no, battery was sitting before starting (12.55), then, after starting, the reading was 14.75, figuring that was alternator charge? trying to give best information I can, from others giving me information as to what to check. will check others you mention, as did another, tomorrow. thanks for your input, appreciated.

OK that's OK for now. These readings are with fans running? Where is the fans power to the relays taken off, pin 30 on the relay?

ON A SIDE NOTE 14.75 is too high. When you get the fans straightened out, either start a new thread on "high charging voltage" or PM me to bump my old brain
