>Dan, thanks for responding, No I do not have a 470 uf cap on 1 and 2 of the Geckos. I remember when I was wiring it up thinking that the leads weren't much over a foot and it shouldnt be necessary. looking at the leads from power supply to geckos this morning they are probably like 24". So these go on the motor leads or the leads from power supply?

POWER SUPPLY! If you put them on the motor leads, you will likely cause
them to explode, and
damage to the Gecko is also likely.

> The 100 uf cap is exactly what blew. Strangely, it never made any more noises today. I ran it all day and it ran perfectly. I went over it closely this morning looking for anything that appeared suspect, took an airhose and blew out around everything and i seen a few tiny chips expelled but thats it. And they werent in close proximity to any electronics.

Yes, since it will be in parallel to the DC power supply.
