Will not start, Valve clearance advice needed. modified 1.7 Options

[Haudiosolutions]

Confusing issue which has been compounded by frequent torential rain and being on-call with 15+ hour days. Short back ground.... Steve and I were attempting to get my valves adjusted which was cut short by heavy rain. When I attempted to start the car later, nothing would happen. The battery seems good. Lights and accessories work. The starter can be manually jumped but I can't get action from the starter by using the ignition switch. The only thing I did out of the ordinary was absent mindedly leave the key switched one click up to unlock the wheel and left it that way for a while but not so far the fuel pump was running. I don't think that would cause an issue but figued I'd throw it in there. There are also two what looks like relays of some sort which I hope someone can clue me in on. The one in the pic is the one up top and the other one not pictured but looks very similar is wired to the starter. I should also add it's a standard points setup.
Thanks in advance for any suggestions. Saturday will be the earliest I could look at it unless I can bribe Steve with cash to get on it heheh (IMG:style_emoticons/default/poke.gif)

Common and re-occuring issue of failing ignition switches due to an EMF pulse that conducts itself back to the igniton switch from starter every time the car is started eventually arcing out the ignition switch./ I have had same isuue twice aboput once a year; and when I bought my 814 it had that Bosch "hot/Hard Start Relay Ugly Relay Dangling, I ditched the realay bought new harness, starter alternator and battery and ignition switch , happened again! left me stranded at a liquor store without warning. Issue had been resolved and I have had no further issues and my car now starts better than ever.. The key is installing a dfiode rectifier that shunts the 350mv EMF pulse from getting back to your switch..

Any electric coil produces a magnetic field when energized. Whenever a switch opens the circuit to this coil the magnetic field "collapses" producing voltage in the field as a" back-current." If the switch is unprotected, the back current tends to arc across the open terminals creating heat and corrosion and eventually burning the switch. A "snubber" diode placed across the circuit diverts the back current away from the switch protecting it.

A diode is a one-way connection (like a check-valve) With the diode placed correctly across the circuit the back-current has an alternative place to go.

The snubber should be placed as close to the coil as possible. It must be "fast" and of sufficient capacity handle the considerable current produced for a split-second by the collapsing field.

This diagram shows the basic snubber circuit. A resistor is on the positive side of the diode, but this is not usually necessary for most 12 volt circuits. Note the position of the diode, which as has been said places the banded end on the positive side. If reversed you are creating a short-circuit!

Dude, your confusing the post with a hijack ... and confusing my input even to me whom is already way ahead of what saying, been through this edjucational proper circuitry lesson previously (IMG:style_emoticons/default/sheeplove.gif) and have done and installed and use every day without fail what I sugessted.. You are coorect that proper electrians traing would imply locating said diode closer to the issue and than even further with seporate straight to ground shunting and solder directly to the soleniod, as per whatever.. I am just protecting the switch with this desighn, there has not ever been a shorted circuit. In fact the previous member whom attempted to correct my uinderstanding, later after speaking to his mentor foudn that proper use of the diode is how I installed it but in said circu\mstance with coil basic protocol would be to shunt as close to the coil. with a direct to ground extension.. The goal for me was to protect the switch not stop the emf with a ugly mess of solder and extra exposed wiring..

If stoppingthe EMF were my goall I would open the coil and do so internally as not to have entire messy look of Bosch style relay all over agin..

As you can see that matters to me that improvement apppear factory and are unnoticable, service able by factory pieces and clean and tight evn to detail with factory oem color metric wiring..

No Frankenstien wiring "proper" or not on my 914, I hate that when I see it because what makes sense to the PO usually as in this thread confuses the isuue..
