Anybody tell me which way the electric flows<br />on a Honda 15hp?,am I correct it starts at at the ignition charge coil then goes to what Honda call the pulser coil (trigger?) and then on to the cdi module then to the ignition coil?,I am trying to troubleshoot a no spark condition and it would help me a lot if I knew the answer to the above, I have a Clymer manual but it does not help in this respect.I would also like to know the maximum gap allowed between the pulser coil and the magnet on the camshaft.Thanks Jim Maw

Charge coil charges a capacitor in the power pack, trigger causes power pack to switch and discharge capacitor voltage thru coil.

Re: Honda Guru needed

To troubleshoot this completly ,you will need a peak reading volt meter ,which is not something most people have lying around. Sometimes these engines get a little corrosion built up on the pickup under the cam pulley.You might try removing that pulley and sanding the contacts with some silica sandpaper.

Re: Honda Guru needed

Clanton,thanks for your response and just what I wanted to know.<br /><br />Hondon,thanks too for your response, I understand what you are saying about needing <br />peak reading meter to measure the voltage <br />from the ignition charge coil but I have'nt got access to one, Clymer manual only gives<br />gives resistance value's and mine is below<br />the value shown in the manual but I do have<br />a spare charge coil and they are both showing<br />EXACTLY the same value's so I am concerned about the reliability of the test.<br />I had the same no spark condition last year<br />on this motor and spent a lot of time and money on it changing the ignition coil.cdi<br />and charge coil,took the wiring harness completely off to check for break's and corrosion and eventually got it running perfect at home,I put it in the back of the<br />car to take it where my boats sat on its mooring,(16 mile round trip) and due to unrelated circumstances<br />I was'nt able to put the engine back on the boat, brought the engine back home and it would'nt start even though it had never even<br />left the back of the car, it took another few<br />days of pissing around with it before I was able to start it again,when I did get it running and decided to change out all the parts what I had replaced and it ran just as well with the old components as it did with the new ones so I am reluctant to spend anymore money on parts.<br /><br />I will definitely check for corrosion under<br />the cam pulley, the manual is very vague in<br />this area can you please take the time to help me further, what exactly is under the pulley, manual says "pulser magnets", nothing's<br />going to spring apart is it? and I assume that timing is 'nt an issue
