Hi all,
This isn't really a DIY project but more of a cheat repair or saving a ton of cash...)
I have two icecap ballast, one drive my white light and the other drives the actinic's, unfortunate for me one died... I checked out icecap USA and found it's about USD60.00 for the repair and another USD200.00 for shipping both ways, so I figured "nothing ventured nothing lost" and open the ballast, I found the varistor smoked.
I made my way to SimLim towers and bought a varistor and had it re-soldered in for a whopping SGD5.00
Now I have lights again and cost nothing compared to either having it repaired or buy a new one.
