Bosch coil

lumpster, Aug 30, 7:29pm
If I plug a lead to the coil and put a spark plug on the other and earth it.it should spark! With ignition on! I think the pack has had better days

you have to feed power to the coil for it to work
NZTools, Aug 30, 7:32pm
No. The coil will fire when you remove the earth. ie break the circut

I'm confused. Are they talking about earthing the plug or the coil in post one!
lumpster, Aug 30, 7:40pm
The coil is all wired up and the lead is on the dizzy I took the lead off the dizzy put a plug on it to see if it would spark
a.woodrow, Aug 30, 7:43pm
Ahhh I see now. So I assume the vehicle had no spark then! Have you checked connections and fuses etc - still need power to the coil if you're going to get a spark

Connect powerto the positive terminal. and eath the negative terminal.Hold the coil in your left hand with your thumb over the HT tower. With yuor right hand pull the earth lead off. If you come back thinking I'm a wanker, your coil is working.

I used to do similar with mower when it didn't start, get kid to hold lead, pull it and if they jump, sparks OK (o:

Yes but no lol

On something like a lawn mower if the keyway has sheared and the flywheel has moved you will still get a spark, but it will be at the wrong time, so the mere fact that you have spark doesn't mean that spark can be eliminated as the reason for the mower not starting.

I know that, but at least I eliminated the coil was OK (o:

And taught the kid not to trust you with things mechanical and electrical again lol

My 4 year old will eventually learn to trust me in a similar fashion. I keep telling him to NOT touch the electric fence. sooner or later he is going to get an 8.2Kv boot off that puppy that will learn him real good. (he's been getting a bit cocky around the fences lately)

I knew an old farmer that didn't mind electric shocks, he never used to bother turning the fences off when moving them. Thought it was a great joke when he got a new farm hand. "hold this a minute will you".

Same guy only ever owned two cars in his life too, Model T then a Model A which he drove well up to his death which was fairly recently, he must have been well into his 90's.

Really interesting chap. I was annoyed at Ford though, someone let them know when he was doing his last South Island tour in the car but they never bothered to do anything for their archives. Pity, it would have made a great short doco or something.

I usually get one or two shocks a day, but workboots these days are pretty well insulated, so it doesnt hurt much. If you happen to be touching something that is well earthed at the same time as you touch the fence, it is a whole different level of pain

Faradays law, so you will need to the magnetic field to collapse for it to work.

A lot made in Mexico etc now. Quality of bosch not what it was.
