Ok everybody, I need a little guidance in the 12 volt electrical department. Being the son of a Master Electrician, I feel a little stupid not being ably to figure this one out. But a little Humility never hurt anyone, so here goes.
The used canopy that I recently installed on my JD 950 has 4 amber lights on it, one on each corner. Wanting to make sure that they all worked, before I ran any wires and made any permanant connections, switchs etc. this is what I did.
I properly grounded all 4 lights to the bolts that hold the canopy to the ROPS, these bolts thread directly into the factory holes in the ROPS, there are no clamps. I hooked a wire directly onto the Posative battery terminal and ran it to the back of the tractor for temporary connections.
Now comes my befuddlement. I can connect ANY TWO of the 4 lights and they come on at full brightness, if I connect the 3rd and/or 4th light EVERYTHING goes very dim. /w3tcompact/icons/hmm.gif
There has to be a simple and logical explanation for this, I have done my fair share of automotive wiring, fog lites, driving lites, wigwag flashers, trailers etc. but this one has me stumped.
My plan / intention is to hook the 4 lights up to a wigwag flasher, but I need to make sure that they will all work properly first.
