WEll I had the buttons out to test the readings on them so i clipped the wires to one side and brought it on to photograph it so I connected my meter to it and get slightly better readings they tended to stay a bit more stable with it out of the car but here are the pics. also ford lists a ohm for each button but i have yet to be able to get the right number for them i tryed adding a resister to the wire and got a constant reading however I can't get one with out one.

Thanks,

ok i was playing with it and managed to get a solid reading of 500ohms if i hold the button for just under 1 sec and it will hold at 500ohms this is without any resisters added

evermind i get a reading of around 500ohms from both buttones on the panel I am gonna get a new meter that is more sensitive tomorrow and see what i can come up with

well I adjusted my analog multimeter turns out it was out of adjustment possibly from being tossed around in the car and started getting a reading on the buttons i took in both gave me the same reading so i took to random resisters i had and soldered to the wires fro them now one button has a resistance of 680 and one has a resistance of around 5100ohms have to find my digital meter for the exact number i will try the same thing with the other button panel tomorrow perhaps then i can get to work building the converter to feed them into my keyboard encoder.

Well if you get solid readings or readings that dont fluctuate as much, I can help with the design. It should be really simple.

thanks i will post the readings as soon as i get a chance to try the others again tomorrow

yonu

ok I got the following readings with the other panel out of the car turns out the buttons were worn out out and moving on the connectors after i fixed that it reads 120ohms on one 2200ohms on the other and 680ohms on one so i have to change one of the one of the resistors on the other panel as it is also 680ohms I will retest the readings after i put the panels back int eh car to make sure they have the same readings

Thanks again,

ok when remounted and hooked back into the steringwheel harness the best i can come up with as i can't find my digital meter and havn't had a chance to go get another one is readings of 2200ohms, 680ohms, 120ohms, and 470ohms those are the readings for 4 buttons i have got to disassemble my wheel again and change the resister on the 5th button as when i hooked it back up it get a reading that my meter can't even register so i will get that one changed a bit later are the 4 buttons enough info to start with or are all of the readings required to know what to get?

Thanks again,
Yonu

yonu

ok got it changed the resistence of the 5th button is 220ohms

yonu

ok the resistances are as follows
220
2200
470
680
120

Thanks,
Yonu
