Problem Testing Steering Motor

[jerryspaghetti]

Any guidance on how to check this kind of steering motor.

Pretty sure the force feedback board is on the fritz.

What voltage does the motor take?

If I can run some power through it just to see it running it will help diagnose feedback issues

Check the voltages on the connect or being fed into it cab side

test mode should run it - check the brushes and make sure it isnt seized.
naming the game or even the make would be helpfull!

Take care with motors, in certain cases older games used mains voltage to the motor. For example 110v for HardDrivin thru an isolation transformer.

 

[Mc-Q]

the voltage isnt really the issue, it's the parts suddenly spining with maybe ½Horsepower behind them!
never try to power a motor that is not bolted-down!

Did you find a twin yet ?
I believe sega Dayton / sega rally is 19v at clutch 100v at motor

Most faults at ffb seven seg pcb
Or the ffb motor driver pcb ..

Lix has done awsome work in custom replacements here

Do you have seven seg on your force feedback pcb .. they throw up error codes

That steering motor looks like it's in an Indy 500 or Sega Touring Cars?

If so, you can measure the voltage coming out of the drive control board itself. It'll be more likely that the board is knackered rather than the motor itself. If the output is low or zero then the board is faulty.

I don't think there's a test-mode page for FFB in Indy500. The strength is set via a dip switch on the drive control board.

Double check both pots on the back of the motor are reading correctly. If the pots aren't correctly telling the drive board where the wheel is then the FFB will not work properly. My Sega Rally's FFB is erratic which is probably due to a noisy pot.

So some motors are AC power and some are DC, should be a sticker on the case with the voltage rating and power type, but you can also run them at a lower voltage than rated and it should spin slower.

Its a Sega Lemans 24

Thanks for the adive guys, I think its going to be the driver board or feedback board so i'll get them tested first and foremost.
