No start electrical problems

I got an 86' maxim 700. Won't start. Just had the carbs rebuilt n new plugs. Had the coils ohmed and they checked out good. When u crank it u can get spark but it's weak then as soon as u let off the start button it sends a big jolt. I kinda think maybe the cdi box but don't know how to test it from here. Any help at all would be great. Thanks in advance.

 

Sounds like your battery is not too happy, you need to get it charged up correctly. The give-away is the large "jolt" you describe. It occurs when the starter motor is not pulling any current and allows sufficient current to really ignite. Check that battery out and consider replacement if it is more than 2~3 years old.

 

Try a jump from a car battery, that will tell you if it is the batt'.

 

Ok. Will do asap. Thanks a bunch. Hope that's what it is. A battery isn't much of a big deal.

 

Had a similar problem with my bike last week,put a new battery in and also found the positive terminal adapter had a crack in it.welded it up and boom,just touch the button and it fires.

 

Sounds promising. Soon as the rain quits I'm digging into it. Thanks

 

ok well hooked it up to a fresh battery today and it didnt work. im thinking its gotta be the coils or igniter. i was told the coils ohmed out fine. is there a way of checking these parts so i know to tell if they're bad? i know u can ohm ur coils but what range do they need to be? and how do u test the igniter. thanks in advance. i need it back up and running bad as its my daily transportation and i cant keep relying on others to take me to work.

ok..i dug even deeper into it and its getting enuff spark to fire the bike. it just wont. there is fuel going to the carb but no fuel getting to the cylinders. so the guy who did my carbs got something plugged up or jacked up. looks like im gonna just go and find a set off a running bike and slap them on and then go from there. thanks for all the help everyone. it was greatly appreciated.

 

Does the bike run when you shoot some starter fluid in the intake? If it does, sure sign of problems in the carbs. If not, you still have ignition issues and new carbs isn't going to fix that.

 

Unless it's flooding really badly - which you can tell easily by the wet plugs. If you've got WET plugs, and spark, try disconnecting and plugging the vacuum line to the petcock, then crank it for a minute or so with the throttle wide open (and the "choke" off) and see if you can get it to catch.

 

my seca 750 was doing the same thing. and what i found out my problem was the relays. the where stuck open. i dont know what your doing to your bike but i ended up just doing a bare bones wire harness. and i dont like messings with electrical things but my bike runs great.

 

Your bike had spark, but was not running because of relays?

 

ok heres the update. i sprayed starting fluid in and it wouldnt even hit. however i looked in the carb throat and noticed that the venturi's were plugged up with silicone. apparently the carb guy used silicone around the o-rings where the fuel rail is to keep from leaking instead of just replacing the o-rings. so off the carbs are and i'm gonna deal with that issus, however the fact that it didnt start with the starting fluid bothers me and i noticed there are no fuses or fuse box on this bike.

 

ok. took the carbs apart at the shop and the silicone so just on the outside. nothing on the inside and the carbs flowed fuel just fine. so it seems the bloody culprit is most likely the igniter box. im gonna call the local shop tomorrow and see if he has a spare one laying around i can use to check it. he keeps alot of parts laying around for the older bikes.

 

What did the plugs look like before you sprayed the starting fluid in?

Where did you spray the starting fluid in, and how much?

You said before you were getting spark on all four cylinders. Is that correct?

When was the last time the bike ran?

 

Plugs are brand new and all getting spark. But weak spark. I pulled the airbox n sprayed starting fluid down the throat of the carbs and when that didn't work I pulled a plug and shot some straight into the cylinder. I didn't skimp on it but didn't put enuff in that it would wash out the spark. Still nothing. It ran a couple months ago and was acting like it was flooding out down low but would clear up as u got farther up the tach. I loaded it up on a truck n drove home. After I unloaded it it never would start again. So I got the carbs done thinking it was a float problem. Which it was, but seems there's more too it than that.
