   Toniet I will re-read the instructions. Heck, I left the rotor off the first 
time.


Thanks Bob,

Jeff

I know nothing about the ignitor, you'll need feedback from one of the 
other members of the list that are familiar with it.

You measure from the "+" side to the "-" side, just yank the wires off 
before you do this to get the correct reading of just the internal 
resistance of the coil - in other words, measure the coil when it is no 
in the circuit...

No offense meant, Jeff, but if you have an open circuit there would be no 
drain on the battery. You might be looking for a short circuit which 
would be draining your battery.
     
To test this, you would measure the total resistance of each of the three 
circuits that the Triumph engineers gave you, there's one unswitched and 
two switched circuits, if memory serves me right.
     
Disconnect the battery. Measure from the fuse to ground... you'll see 
some resistance or possibly an open circuit. If it's open (infinite 
resistance) then that circuit is not your problem. Once you isolate the 
circuit - then you can start pulling wires from things and see if the 
resistance goes up to infinite when you yank a wire or two. By 
methodically doing this, you can determine which circuit is shorted.
     
But we're getting ahead of ourselves... you've only been playing with the 
ignition circuit, so that's where you should be looking. Disconnect the 
battery... go to the switched circuit at your fuse box. Measure from the 
fuse to ground... get a reading. Pull the wire off the "+" side of the 
coil. Did the resistance change? If so - you've identified the problem. 
If not, yank another wire in the ignition circuit... and so on.
     
If the situation is hopeless (meaning that you can't figure out what the 
heck is going on), call AAA. Any competent mechanic should be able to 
troubleshoot your ignition problem. Get your car hauled there or look in 
the Yellowpages for a mechanic that makes housecalls.
     
I will say one more time - make sure that you understand what the 
installation instructions are telling you. When I installed my Crane 
system, I had connected the coil wires wrong... when I went back and 
double checked my work, I identified the problem and fixed it. As you may 
surmise - the car did not run when it was hooked up incorrectly.
