There's hope yet!
I decided to check the dew straps for correct operation. The Firelite 2" I was using on the lenses gave fluctuating current draw when I put the Fluke on it. Resistance check didn't tally with my other straps, and was variable. I pulled the strap apart and found the fitting that crimps on to the resistor film was not fully crimped. There was also just some electrical tape used as insulation, and this was not even between the two contacts, so not only was there intermittance, there was the likelihood of short circuiting as well, as the contacts are a fraction of a mm apart.
So, I crimped the contact and put insulation between the them, and now it's working like a charm.
Unfortunately it looks like this has caused a fault in the Kendrick controller, and even though it is meant to be able to supply 5A per channel, the whole controller will only supply 720mA, which gets shared across whichever channels are active. I can't say I'm overly impressed with the Kendrick quality control.
I'll give the 100mm another try with a fully functional dew strap.
Cheers,
Jason.
