I hope this helps. Setting up a chip etc, time consuming. I'm going to make a thread on testing connections. It make take me a day or 2, this is going to be a crappy, crazy week for me......

Great !!
Please tag me then...

Xxx you should test the cobs voltage in between each cob. As Pop mentioned double check all connections and possibly disconnect the dimmer to see if that is a problem. I know the timber lights came with a ground wire attached to the dimmer which they later told people to disconnect. I guess it lowered the wattage. Not to sure about that but besides loose connection I'd say possibly a dimmer issue. They are cheap.

I'll try this.. but before I installed the dimmer I was trying connecting the power, and in my eyes there was no different

A watt meter is handy, but may be misleading also. Enough resistance from poor connection will actually increase the power draw. Everyone who is going to work with electrical components needs a volt/ohm meter and needs to learn how to use one. Probably the most important tool you can have for this.Most electrical problems can be solved with a meter.

I would check voltage at each cob. Testing the string MAY tell you something, no test is to be ruled out till an answer is found.

@pop22 I was thinking... how about you make a watt meter video. And place this into a sticky tread ?

Got it
Why did I not think about this

Should I test both voltage and resistance ?

you should test the resistances of each cob and of each length of wire when it's not on, then of the entire chain.

The voltage is best tested when there is a current.. be careful with that though.
Best to not ground yourself when playing with that.

Okay
And yes I am

I have spent so much time trying to figure it out. To be honest it's the first time I have heard anyone say they weren't blind for atleast an hour after turning even one cob one. Flip the meter on and turn it to dc volts 1000 and check between each cob. You could try and run just one cob at a time to with that driver too. Unplug it and add a second, third.
