okay i can set the timing w/o the est wire hooked up,and it runs great! burns tires really well. but as soon as i hook up that wire forget it it wants to fall on its face ,and if i turn anything on (heater ,wipers ) it dies. but if i leave it unhooked everything works and motor doesn't die. can i run it w/o hooking that wire up, or will it mess something up?

 

What does the timing do once the EST BYPASS connector is re-connected? Check it with the light.
