Pioneer KEX-900 blowing fuse

dhamia · 14th October 2010, 07:31 AM

Hi, My KEx 900 was working fine, it now keeps blowing the B+ fuse, the deck is too nice to scrap any ideas on what could be the problem?

Was any work done on the vehicle about the time that the head unit began blowing fuses?

No the unit was not installed, I just tested it the other day, one day it worked fine the next it wont power up and keeps blowing fuses

Measure the resistance on the memory and ignition wires. Place the black probe on the case of the head unit. Touch the red probe alternately to the memory and ignition wires. Do this with no power applied.
