Hi all i got a high speed a few years back, and when i bought it, the police light was ALWAYS on when powered on. To save the motor from burning out, i unplugged the motor/light.
I played the game without the beacon light since then.
I finally have The time to look into fixing it.
The police light motor/ light operates as solenoid #4, although it is not a solenoid.
The light uses transistor Q24, and pre driver transistor Q20.
Originall i tested only Q24 and it was bad, so i replaced it.
After putting it all back together, it didnt fix the problem, so today i tested and replaced predriver Q20, and retested Q24 from .4-.6 volts, but the light still does not run.
The light is controlled through J11 pin 5 grey/yellow wire.
The grey yellow wire runs up to a small wafer type board next to the light.
The board has a diode and a ceramic resistor on it.
It then sends the signal to a relay next to the board through a greywire snd a brown wire.
When the signal is received, the relay closes, then sends power to the light by two red/white wires that connect to the police light.
There is a fuse on one of the red/white wires, and the fuse tested good too.
When i bypass everything, and touch the pair of red/whit3 wires together, the light lights, and the motor spins.
This means that the motor, bulb and red/white wires are all fine.
When i operate the relay using a 9volt battery, the light and motor work fine too, so i believe the relay is fine too.
I checked continuity of the grey/yellow wire from J11 pin 5 to the wafer board, and continuity is good.
Now, before i test the diode and ceramic resistor, Id like to check the output of the grey/yellow wire from J11 pin 5 to the wafer board, but not sure how to do so.
If anybody can tell me how to test this id appreciate it.
If i left anything out, just ask.
All other solenoids/flashers/lighting are all fine. Only the police light issue. Thanks. Sparky
