another problem wont start

[f16dcc431]

on my 76 850 it was running pretty good just a little rough and it needed a new impeller so i decided to by the impeller and some new plugs. after replacing both items i went to start it and had a hell of a time getting it going but it did get running but then died i was guessing because fuel.... forgot to re hook up fuel hose dumb me. but now im not getting anything when i was cranking it the ground got a little hott from over using it so i just let it cool off. I think i may have screw somthing up. because now it will turn over but no vroom vroom. im guessing to put a spark tester on it to see if that works but any other ideas all i did was the plugs and impeller oh yea when i pulled the old plugs they were real loose could it have been that by them beaing loose the gap was bigger IDK they are the flat plug type.

I recommend a compression and spark test. Let's see what we are working with.

all compression is good spark with a plug is not there at all

Re: another problem wont start

I have put my spark plug wires on wrong before think I would check wiring first. !

Re: another problem wont start

so i have no spark on any of my plugs so i put a multimeter on the wire going into the coils no power can anyone tell me the steps to troubleshoot the ignition system and maybe tests to check if its the stater trigger box or maybe just a wire

I look at a motor a littler older an your a day ago and I would check first see if getting voltage to coil, down the line voltage to switch and so on check for spark on dis, points, I know you would think no but could be bad dis . a service manual are great to have . I have one for mine but I read this ever day. hope it help you

Re: another problem wont start

I need to know how to ohm the diffrent ignition parts i bought a manual but have no clue what ignition system i have

Re: another problem wont start

how can i test the switch

Re: another problem wont start

i googled testing rectifier and acording to the test i have a faulti rectifier would that affect spark

Re: another problem wont start

if it ran good before it should run good again, check the easy stuff,is the handle in neutral? i would check the kill wire first before anything.

Re: another problem wont start

yea it turn over just no spark were is the kill wire

Re: another problem wont start

OK, Lets make sure what we are working on. That motor has 4 coils, right? Disconnect the yellow stator wires at the rectifier, anf tape the to insulate them from each other and ground. See if spark returns. If not dicsonnect the orange wire at the switchbox and the mercury switch. Mercury switch is a blue cylinder, usually mounted on the front cowling support. See if spark returns.

Re: another problem wont start

i have spark!!!!!!!!!!!!!!! motor is running found a broken wire causing the recitifer not to work yay like always thanks guys for the help
