On my 2002 Saturn L100, the passenger headlight is only showing 5 volts instead of the normal 12 volts, whats wrong ?

bad ground wire for the light
check both sides of the bulb as one will be 12 volts and the other considerable less because of the high resistance of the filament of the bulb

No power electric

If the scanner is plugged in and seems to have no power, then the voltage control board is likely burned out, the scanner runs on 12 volts Direct Current and so house power is converted to the DC 12 volt. Unless this is a very high end scanner fixing it is cost effective, scanner and all in one printers are so cheap it just doesn't make sense.

I was curious, if i put my 2055 scanner on 12 volts, instead of the required 13 volts, will it hurt it?

You won't damage anything with 12 volts. Equipment built for use in automobiles will often have a DC input marked 13.8 volts because it's the voltage delivered by a fully-charged battery. But any supply around 12 volts will work. Just be sure the supply has enough current available (around an amp should be fine for a scanner), and that you get the polarity right when connecting it.

Can kicker 1000x1 amp detect if my speaker is bad and turn itself off?

The Kicker 1000x1 Amplifier does not turn off if their is an Open Line (blown sub) on the Speaker Terminals.

  1. Remove all Speaker Wiring from the Amplifier, leaving the Power, Ground, Remote, and RCA wires plugged in.
  2. If the Amplifier fails to turn on, check your Remote wire for power.
  3. If the Remote wire is powering up with the Head Unit (should be anywhere from 5-12 Volts), check your Power wire for +12 Volts, and check your Ground wire.
  4. If you are getting +12 Volts Power and your Remote wire is putting out 5-12 Volts but your Amplifier still won't turn on, it will need to be serviced.

I’m happy to help further over the phone at

Mits 527252 ballast

Good Day; I would suspect the ballast, but try these first:

Causes: Cause #1 1. (Lamp may light and go out) suspect bad lamp part # 915P020010 2. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977010 3. (Lamp may light and go out) Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if low or missing check C9A37 and C9A38 both 3300 UFD 10 V part # 181P732040 on the Power PCB (part # 930B921002) 4. At power on the lamp turns on and off three times and then the unit shuts down with a red lamp LED (lamp error). Replace the Light Engine part # 939P977010 5. Lamp enable line at J14 pin 6 does not switch to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 6. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on and does go to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Lamp Power PCB (ballast) part # 939P978010 7. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010. Good Luck, big IRISH.
