8n convertion trouble

[rickho]

Converted my 8n ford front mount distributor to 12 volt electronic ignition. Worked great for one year then started to have starting problems. Now it won"t start. Jumped the resister and it started up. Ran for a while and now won"t start. Do you think the coil was getting bad? and if so should I add a second resister in the line after I put a new coil on?

" Do you think the coil was getting bad?"

Unless you are in the habit of leaving the key on, no. And if you are, then the EI is probably toast.

"and if so should I add a second resister in the line after I put a new coil on?"

No. The EI has specific voltage requirements; just randomly adding "a resistor" is wasting time & money.

Post back w/ the make/model of your EI unit. And tell us what the voltage is going to the coil. JMOR will be around soon w/ his EI troubleshooting guide.

what coil and resistros do (did) you have?

(quoted from post at 14:39:46 10/10/13) what coil and resistros do (did) you have?

Square 12 volt with a 1.5 ohm resister. I did replace the coil and it started right up. You don't think I need an extra resister? Just wondering why that old coil burnt up.

depending ont he coil.. you may be a hair high on resistance.

many 12v square coils are 2.5 ohms. add that to your 1.5 ohm resistor and you are at 4 ohms. Ilike to see more like 3.5 ish.. however.. if it starts and runs.. i would stop fixing it at this point.

I will let it be and see what happens. Thanks
