Ok well i would check for a open diode in the main ac to dc power supply then check all resistors that look lick they may be low ohms but high watt check to see if you might have a open pico fuse from primary power supply to the regulator check and see if you have stand by voltage this would be easily checked on the power off oan on button get back to me k

40 amp. fuse keeps blowing out on 2008 harley


You have a short. Check the insulation on all wiring that carries + voltage - possible that some wire may have lost insulation and is abutting some metal part shorting it out.

Fuse 12 20A keeps blowing. controls OBDII and cigar lighter


Hi John!
  • There is a short in the Circuit. Do not put any more fuses in it.
  • Take it to the Electric Shop to have it diagnosed.
Good Luck,

Can a bad voltage regulator cause the main 30 amp fuse to blow?


Usually a bad regulator will only cause problems with charging...
Sounds like you've got a short somewhere in the wiring...I'd start by checking the ignition switch wiring and the connections going into the fuse box.

No power fuse blew


it means you have shorted regulator transistor on power supply..

It is usually fit in heat sink..

Try to replace it and the fuse again also check any fusible resistor near that transistor..

RCA P60752EB Power problem


Apparently, blown fuses indicate problems elsewhere in the circuit. The block is a voltage dropping resistor, has nothing to do with problem. If you think it's worth it, take to pro/tech

No power/RCA ctc187cl


Check for 5 volts present at pins of EEPROM IC. ( 8 pin-center
front) = no 5 volts = Re-check power supply components such as AC in resistor 2.7 Ohm ?....Or 5 volts ok,then suspect EEPROM corrupted........part # 223957 ( install 8-pin socket,then re-plug in original, if that doesn't clear it, plug in
new part) Use pre-programmed after-market replacement,if you 
can get it.....Let me know....T.

Instantly blows the 5 amp fuse next to the power cord plug.


You have a short in the power supply. Look at the regulator and or rectifier diodes. These are all on th primary side of the SMPS (switched mode power supply) the secondary side if shorted shouldn't cause a blown fuse at all.
