new here! several questions

Sounds like you are using the reed switch to carry the current ... this never works.
What you need to do is add a transistor to carry the current and use the reed switch to trigger the transistor, you may also need a resistor in there.

When i started i used an old, but new version of, the english SU fuel pump which had a coil and the reed switch and all the circuit that made it work, even then i soon killed the reed and found i had to go buy some really big ones to cope.

nice, thanx for the info.

i can see what you are talkin bout and im thinkin the fuel pump can be replaced by a simple relay to act as a reed.  heres the thing, doesnt sound like you recommend that anyway.  so you think i should use a transistor, got any good advice on what i should look for?  part number?  maybe a video with setup and parts?

i am glad to know that i am not the only one tho.....  ill tell my wife im not crazy...   =)

the reed switches i have from the link above are pretty good right?  that was the biggest current ones they had.  but i know that i can see the spark when it latches and im positive that it is sticking because of the current load.  so you mention using a resistor.  can you jog my memory a bit, is the resistor to limit the base of the transistor or the load/emitter? 

i have seen many videos with a transistor type trigger.  is that the best practice/way?  only reason i was using the reed is because it was simple and i was just tryin for any type of result.  didnt get too far.  maybe i need to order sum transistors, or just scavenge them from old stuff.  i have a lot of old boards.

please let me know, i like where this is going.

and just in case someone whats to know where my inspiration comes from...
primarily these two youtubers:

I suggest start simple ... the link here has a clear enough view of the transistor circuit for you to start with

With this the load is taken by the tranny and the reed is only driving the tranny not the motor.

from there all you need is a diode connected to the + side of the coil so that when the battery is connected there is no reading on the meter and then connect this to a bridge rectifier and then measure the dc coming out of it ... the diode only allows the reverse current to flow back to the charging battery

Once you see there is output without increasing input you will be hooked

sorry, i cannot see that video.  blocked in the US, it says. 

thanks for the explanation tho, im gonna start gathering parts to give it a shot.  hopefully this week.  im pretty sure i understand what you are explaining.  i will post back when i get frustrated.... 

you said "tranny", that makes me laugh.

thanks again.

search pulse motor circuit on youtube .... i found a few that clearly show the circuit and some with diagrams
