Ignition issues after unknown pop.
-I rendered the Ignition switch on a 94 Civic cx to be the culprit of a randomly dying car. With little time and money I decided to bypass the switch altogether via bringing ACC,IG1,IG2 together on a toggle switch and a momentary contact switch for the starter. The issue came when I ran the White wire (power source) to both the toggle and the momentary switch. Initially, In turning on the toggle, all systems were go. the fuel pump came on dash-lights, etc. However, when the starter button was hit, I heard a small pop from what sounded like the engine bay, accompanied by no electronics, at all.
-The crazy part now is that I get electronics intermittently but as soon I attempt to draw any further power (headlights, etc.) all systems die followed by no response.
-I do understand that splitting the power to both switches was a dumb idea and clearly caused the headaches. When I get systems back online I plan to run the starter switch as a separate entity.
-I've checked all fuses, nothing seems out of order.
=Im not much of a wire-chaser but any input would be appreciated.

But first, restore that wiring nightmare you caused.

Re: Ignition issues after unknown pop.
Nice, Grumblemarc.
-I do plan to have all back to speck but transportation is of the utmost. The ignition switch is on the way from Canada and about 5 days out.
-I have the power wire disconnected and away from the starter wire.
-Does anyone else have any leads as to what might be causing the electrical intermittence?
Again, Thank you.

Re: Ignition issues after unknown pop.
My guess is that the toggle and momentary switchs you are using can not handle the current.
Splitting the power lead. [white] to the toggle and momentary should not be a problem, the stock ign. switch does that.
Having ACC,IG1,IG2 all together may be a problem, as the stock switch cuts power to ACC and IGN.2 when cranking to start.
Because of the small pop from the engine bay and a loss of all power when system is loaded up, "attempt to draw any further power" I suggest you check/redo your main grounds, [batt. to chassis, chassis to engine. 94
