    Re: 12v 1uo941243c Relay repairable?

    Most likely under the hood near the battery

    And a number will be on the top of the fuse or on one side of the fuse

    They will not look like the lower amp fuses

    I just got done installing a car stereo in a semi truck that the engineers thought it was cute to do all the speakers wire green including the power on all the time the ignition switch power the negative side was white

    This only took about an hour for me to figure what wires went to what speaker plus the negative and positive side of each speaker and what wire was power on and the ignition switch power supply with out a wiring diagram but I have many years of experience doing troubleshooting and having the skills that are needed

            Check all of the high amp fuses there was a time way back when they used fuse able link instead of a high amp fuse this much hard to find because they can be any where in the car

                            Three 30A ?, the bigger ones are the metal strips.

                                  you mean that in addition to the 30amp fuses those metal strips are those high amps fuses?

                                    just measure the voltage on the large terminals where k20 relay plugs in . one should be 12v . the other is going to be shorted to chassis if the fuses have been replaced that blew first .

                                      you need to find and fix the short before blowing more fuses .
