2020 Seneca Disco Light

[75462]

I could not handle one more day with my Led Disco lights. I didn’t want my RV to sit for weeks at the dealer for this. I ordered new voltage regulator IC chips and fixed them my self for a few bucks.

Good thinking, DIY is the way to go. Why park at the dealer while you can camp somewhere.

Especially when you have the skills to do the job!

What was the issue you were having?

Constant flickering with three LED fixtures so far. I have replaced the voltage regulator on the board with great success.

Every one of your failures was the LM302? that was it??? are they failing because of heat (no heat sink)?

I have a few more that need this fix... way better to put a 50cent part back in the light than a $20 replacement that won't last any longer! I prolly have 1-2 back at home left over from an old project.

Yes, the LM317 is failing. I suspect poor quality. I purchased mine from Texas Instruments $.50 ea. The entire disk with LED’s is the heat sink.

ahhh thanks for correcting me... I have a bunch of 302's they wont work to replace the 317

Our lamps don't have any heat sink on that... and the housing is plastic (like the old bakelite material)

Using the "what - if" principal if more heat dissipation would extend the life of the regulator chip. or should I buy a bunch of spares and stuff them in one of the motorhome's cabinets in anticipation of another failure - and consider it a sacrificial component of inherently bad design???

I already carry a low W soldering iron with us in the Seneca.
