Have a cheapo dial meter, and, a Craftsman professional 73756 clamp meter. I can't tell which is right.
I had a coil that I'd removed years back and I think now I understand what's wrong.
Spare coil.
Craftsman:
I touch the top of the coil to the pigtail and get 1200 ohms (1.2k)
I touch the top to the inner tang and get about 1300 ohms
I touch the pig to the inner tang and get about 1300 ohms
Cheapo meter:
I touch top of the coil to the pigtain and get 0.
I touch the pig to the inner tang, and get 800 ohms
I touch the top to the inner tang, and get 800 ohms
Current coil.
Craftsman:
I touch the top of the coil to the pigtail and get 1800 ohms (1.8k)
I touch the top to the inner tang and get 1200 ohms
I touch the pig to the inner tang and get 1200 ohms
Cheapo meter:
I touch top of the coil to the pigtain and get 0.
I touch the pig to the inner tang, and get 550 ohms
I touch the top to the inner tang, and get 550 ohms
Based on the current coil at 1.8, assuming 7.5V operating, with 1 resistor, I'm showing 2.67 amps. Operating without a resistor puts me at 4.166 amps.
Using the old coil, with 1 resistor 7.5v/(1+1.2)=puts me at 3.4amps.
What should I do?
