no spark..

[Jet Star]

coils and points look brand new. i cleaned the points any way and they apear to have correct gap although i havent used a feeler guage to check, the coils showed 1.3 ohms so im thinkin they are good condensers looked really old so i replaced them today and im still not getting any spark been tryin to get this thing running for like a month now. any suggestions

Re: bad starter?

Quite a few starter problems can be traced back to electrical connection problems. Make sure all connections are clean and tight, make sure the battery is in good condition.

You may want to check the Top Secret Files at the top of the page for more assistance.

Re: bad starter?

top secret files has been very hepfull i will look there for starter info,
i did my wireing yesterday and im 99% sure on my wiring, batery is a month old 12.6v thought i had a bad solenoid replaced that and made no difference im getting continuity between the starter casing and the pos terminal couldnt figure it out when dissasembled

Re: bad starter?

When you took the starter apart did you look at the brushes carefully...the positives ones especially...was the copper wire covered in a casing and no open spots on it...the negative ones will be bare..but the positive ones must have a sheath on the copper braided wire..one bare spot hitting the starter casing is bad news....if brushes are bad get a new set...wash the whole starter down with CRC electrical cleaner..blow it out ....install new brushes....a little dab of grease in the lower bronze bearing oil in the top one..take 2000 grit paper and lightly polish the commutator..and spray it clean after doing it...

if done right it will be like a new starter....cheaper to rebuild than buy new..and careful when you buy used..you may end up in the same boat in time....

LOOK at them brush wires...99% of the time it is them either broken or insulation has broken down....

You have a short in the starter. Should not be continuity between starter housing and pos. terminal.

Re: bad starter?

thanks al verry good infomy starter looks like it could use that treatment although now i figureg out the starter is fine i tested directly to starter and it engages, when i re installed and wired up the solenoid just clicks once when i tyr to start with key and starter doesnt engage than when i unhook the ground from battery motor is a 63 johnson 28hp its gotta be either my keyswitch or a mix up in the wiring theres a green wire from pos solenoid terminal (same side as the power from batt) that green goes to "B" on keyswitch then i have a white wire going from "st" on keyswitch to one of the center terminals on solenoid and continues to the vac switch on motor

thats what i thought but then in worked fine when i tested it straight to battery

Re: bad starter?

ya its gotta be a short just tried to test pos directly starter while the positive was still hooked from starter to solenoid and didnt engage starter just click solenoid

Re: bad starter?

i will take it apart tomorrow and check the brushes now that i have a better idea of what to look for hopfully i can solcve the problem

Re: bad starter?

wow i feel dumb. i just had a bad ground, at least my starter got a cleaning

Re: bad starter?

Glad it worked out for you Jet Star..Thats why its told in here to check cables and connection first and make sure clean...

yes the starter is clean all the brush dust is out...last you awhile now....

good luck....

Re: bad starter?

starter works fine now but motors still wont start, im not getting spark. but the points and coils look brand new, maby they arent set right? they look to have correct gap but maby they arent opening and closing at the right times? how do i test the coils and condensers to see if they are good? baby the points just need cleaned but my luck isnt that good

Re: bad starter? ... starters fine, now ign trouble

Re: bad starter? ... starters fine, now ign trouble

motor is a '63 28hp johnson rx-11. the manual say to test with an ignition analizer, lol i have a multimeter anyone know what the resistance should be on the coils? both read 1.3 ohms

Re: bad starter? ... starters fine, now ign trouble

ok should there be any resistance beween the lead and the casing on the condensers? im thinkin yes. checked all 4 condensers between 2 motors i have and none showed resistance checked the condensors on my motorcycle and got readings from them so this tells me all 4 are bad, coincidental considering i keep hearing condensers rarley go bad. i think the guy who had the motor before eplaced points and coils but never bothered to get new condensers, i think they are original (part number ds-581419) i also did a little test using a 9v battery against the lead and casing for a few seconds then touch the lead to the casing to check for spark but nothing maby i need 12volts to the condenser but i think they are shot

Re: no spark..

i edited the original post. but new condensers in and im still not getting any spark everything apeas to be good under the fly wheel. maby my plug wires are bad
