PS 3 LED Question

Dave,

You can test the LED by swapping it out with the LED on the opposite end of the engine.  Front has a blue plug, rear has a green plug.

If the LEDs work then the problem is on the board.  FETs on PS3 boards cannot be replaced and the board would have to be replaced.

The small board where the light plug into has no circuitry on it.  

Good luck,

Dave 

I'm not trying to insult you, but there is a button on the remote that turns it off. It's a long shot, but a possibility.

No worries John........sometimes I do miss the simple things but no the button is on.

Did not think of trying that Dave and just did.  No joy........rear lights work but when I plug in the headlight harness - no lights.

What voltage are these LEDs and might you know a source?

I could wire new LEDs in if I could acquire them.....otherwise it's a new harness from MTH.....and that takes a while....if they have it.

Thanks Gents

Dave

The LED's are standard white LED's for the headlights, you can buy them for a few cents and simply wire them into the harness.  No need to replace the harness.

Dave,

If the light works in the rear but does not work in the front, then the problem is not the light, it is the board.

 Be sure to check that all the wires are soldered to the terminal board for the lights.  If they are all in tact, the PS3 board needs replaced.

I get most of my LEDs here. I put 3mm ww ultra bright in a PS2 GP38-2 with great results. You could probably put the rear lights up front until you decide how to fix them and have the engine looking better going forward.

Dave it seems he's saying that the front LED didn't work plugged into the connector for the rear, that seems to indicate it's the LED and not the board.  Perhaps I'm reading this wrong, but that's what it appears he's saying.

Thanks Dave - GR John is correct. 

John H.....thanks for the link however as seen here in the pics - lots of LEDs with the "lip" at the bottom.

However, I cannot seem to find the ones MTH uses without the "lip".

You need these to slide all the way into the lens holder  -  pics clarify.

Time to improvise .................. 

Look for "flangless" LEDs, I buy them on eBay, here's the place I got mine: eBay # 321711332163

 I keep a stock of warm white, white, green, and red in 3mm for these situations.

Before I had these, I used to file the flange off, but it was somewhat of a PITA, these make the job much easier.

Good tip John...........on my way to EBay.

"Flangless".........better description and "lip"........ 

Thanks

Dave

FWIW, for setups like that, I like to eliminate that lens assembly and use the LED's directly in the shell.  They give a nice focused beam with much better definition without that extra hunk of plastic.

You can use flanged ones and from with exacto. G
