While trying to test the 2 auxillary fans in front of the radiator on a '91 190E 2.6 I'm refurbishing, I connected the battery to the harness end of the connection rather than the fan on the passenger side fan connection (I think one fan is for the A/C and the other is an "emergency" fan for when the motor gets too hot). What might I have damaged? None of the fuses appear to be blown in the main fuse box.
