Hi All,
I am currently installing a Dash2Pro into my track car. The only thing i seem to be struggling with is the brake warning light. With the original cluster in place everything works exactly as expected, the warning light goes on and off with the handbrake and fluid sensor. However with the Dash2 the light always stays illuminated. To wire in the Dash 2 i have used a spare instrument cluster and soldered the connectors onto the back of the instrument PCB to pick up the majority of inputs, thus leaving all the existing car wiring in it's previous state.
The parking light gets a constant shared ignition positive and is switch to ground via pin 3C. This is the middle small plug that goes into the cluster, and is a blue/yellow wire. Checking the continuity of this wire with the handbrake on there is no resistance to ground as expected. With the handbrake off however i'm only getting 500ohms of resistance. I suspect this was enough on a standard bulb to cause it not to illuminate, however not enough on the Dash2 for it to notice the change.
Is anybody able to check the same on their car to see if it is something i have a fault with (shorted cable somewhere) before i start trying to trace a fault that may not exist. The other question is, does anybody know if i can increase this resistance somehow using some resistors or similar, maybe using a pullup resistor and the 5v reference out of the dash?
