Z case fuses , on battery post : 100A / 125A / 250A ,
. All three , including shipping is $25.82, better than dealer
what would happen if he unplugged the connector and put 12 volts on it to test if fan motor turns ,??
would he still need to put some voltage on the little grey wire too , to determine the speede at which the fan turns ????
( considering the fan motor can turn like a boeing ..The EcoDiesel uses a 850 watt fan (71 amps) that uses that 100amp Z Case fuse )
