Try this:
- Clean off the cable terminals with commercial contact cleaner
- clean off the camera sync terminal with contact cleaner. Use a paper or q-tip made to not leave any lint behind.
- Use a twist tie to "aim" the peanut towards your trigger flash light source
- Replace the cables with better quality ones
- You're going to laugh... I have a $5 peanut trigger that I use to set off a METZ 45, and its DAMN consitant. I can get it to trigger consistantly from 5-10 feet away at 1/32nd power off the built-in flash from my D200 and the Metz/peanut trigger on the floor behind our kitchen table!
Here is something for you to consider... modded Poverty Wizards (Gadget Infinity), anyone? I have 1 trigger, three 4-channel and two 16-ch (for the studio strobes) coming within a couple of weeks. Thats enough to trigger 5 light sources!
Total cost? $157... SHIPPED!
I'll do the easiest/quickest mods after measuring real life performance before and after, but man, there are just too many people having a good time with them!
