Last night the dashboard instrument lights, parking lights and tail lights on my 72 240z shut down when i turned the combo switch on. I noticed that the 15 amp fuse inside the fuse holder provided by Dave Irwin Parking light harness kit went south. Replaced it with another 15 amp and even a 20 amp fuse dashboard lights, tail lights and parking lights came in for 2 seconds and the fuse went out again. I believe the problem resides in the harness upgrade. Last time this happened i removed it from the circuit and connected the stock female and male 6 wire connectors together and all the lights came back. Could there be an issue with the relays provided in the kit? Should i just check the parking light bulbs first and clean for any corrosión before removing the steering colummn cover and making the straight stock connection again?
