Module Over Temperature

<< < (2/2)

BruceRogers:
I've had module over temp issues as well. If you're using the older pre LED lighted locomotives the problem is caused by the incandescent bulbs. If you run you locomotives for long periods you'll see it rise. I you turn the lights off the temp will drop if you want to do an easy test. I've changed most of my lights out for LEDs. Never had a problem since.

Espeelark:
Thanks Bruce - yes, this Athearn GP40X has stock incandescent light bulbs and has qty -8- when you take into account the SP light package. I will give that a whirl and see what that does (after I get to the bottom of my intermittent shorting issue).

As an aside, what kind of LED's do you use/install? Make, model color?

Thanks!

Alan:
If you are up to it you could use a simple transistor circuit on the LM output pin. That would let you run as many incandescent bulbs as the transistor can handle while the LM happily sees little load.

[EDIT] My bad. Accidentally posted active high driver diagram. New diagram is active low and would actually work.

BruceRogers:
These are the common warm white LEDs I use. Purchased off eBay.
