PS32 Lamp Capacity

Six bulbs are a bit much, I'd suggest a different path.

You can set the ditch lights to always on in the configuration, did you try that?

If you can't get that to work, I suggest replacing the bulbs with LED's and then you can wire them all together.

The number boards are set to always on, the problem is the lamps are tied to the ditch light circuit.

I have extra LED lamps from other kits, I'm assuming I would convert the interior and number boards to LEDs and drive them from the interior light circuit?

Also, each LED needs one 570 ohm resistor?

You can set the ditch light circuit to never flash which should solve your problem with no modifications.

I did suggest that...

For PS/2, each LED needs a 220 ohm resistor.  The lamp average voltage is 6VDC, it's a PWM signal.

Tried that in the handheld- didn't work - the lights still flash with the horn. The tablet does not even indicate ditch lights as an option, just interior, marker, and boards.

This simple board upgrade was complicated when I damaged the top board which knocked out the tach reader. I ordered a replacement board which fixed the tach reader and everything now works perfectly minus an uncooperative ditch light circuit being assigned to the number boards. I thought about researching the wire assignments, but at this point, I am good to try what John has recommended in multiple threads.

Sorry for the long story but thank you for the help!

Sorry, I started my reply but didn't get back to it until much later..

Yep, I tried programming the ditch lights on a PS/3 diesel, apparently there is no setting that leaves them on all the time.  Odd, as I remember some PS/2 engines allowed that option.

Using ADPCM.exe, wouldn't it be possible to edit the softkeys of the engine's PS2 file and then load that modified file to change the Markers and/or Ditch Lights output behaviour?

I've not heard of this. What are the steps?

You could use an original PS-2 3V upgrade file for your model to fix this.  Or, if you had a board tester you could see if other output are the number board.  Besides Ditch lights, the MARS output could have been used for the LNB.  If so, you move the ditch wires from the 8 pin to the Mars outputs on the 8 pin.  The PS-2 3V upgrade instructions have the output diagram.  G
