Need advice

[Almaty_kz]

 

Hello, guys!

Found some problems with ignition on my GSX1100 and took off the coils to test.

Got next numbers (please see photos)

 

According to manual, kindly provided by agemax, the numbers are to be:

Now 2 main newcomer's questions:

1. Did I proceed the test in the right way?

2. If I need to change the coils is it possible to replace them with other model ones (except DYNA)?

Thanx, please don't kick too much)))))

They ain't like any GSXR coils that i've ever seen? Numbers ain't the worst - what about across the LT terminals? They do look fairly ancient / rough round the edges? Maybe blasphemy but get some  h o n d a  coils - direct replacement and NEVER fail, just change the plug caps to suit.

they look like old gs coils

Thats what I thought or Zed - certainly that era!

My GSX1100 was born in 1981 )))))))

That is why these coils look ancient I guess.....

Why the fuck did I read GSXR and not GSX - DOH! Anyway - answer the question LOL!

@1. Yes

@2. Of course.. Plenty of coils from other bikes with similar spec.. But these look like regular '80-'84 GSX750/1100 coils to me..

I think the measured resistance as such might just be fine as -looking at the pics- the stock caps have been swapped for NGK resistor plug caps.. It seems these NGK replacements for the OE caps have a lower resistance..!

BUT the problem with faulty stock coils often only appears in hot conditions (and it can get pretty hot in between the engine and the tank!).. Heat makes broken contacts open up as parts of the coil expand.. To really test your coils you need to recreate the conditions on the (hot) bike, so warm up those coils and measure again..!

Brilliant and true))) I will try again as you advised. Thanx a lot

I had a resistor cap go bad and measuring from cap to cap presented as a bad coil. When I pulled the caps off and measured from the bare wire ends, the resistance was in spec. I also found a lot of corrosion in the caps and at the wire / cap connection.

Thanx, pal. I will check both))

Some good advice there! Will be watching with interest!

If you have to change the coils the ones used on many Kawasakis from the late 80s on are good. Unlike some Suzuki coils, the leads are easily replaceable and you can even use Taylor or Dyna leads with them. I use some from a ZZR1100 and they work fine on an efe engine.

Thank you, pal. For better understanding could you kindly send me (personal mail) the example of coil that suits me on your oppinion?  Best

they look exactly like mine (GSX750S) coils... i measured mine a week ago... I have exactly 30k ohms on both. (on the other side 5 ohm... ) so Yours are out of specs. But I have no idea is this really bad:)

[Madb]

i would say them coils are throw away. too low resistance.  cheap enough to replace tho.

[Almaty_kz]

Thanx guys!

[Almaty_kz]

I say, gentlemen, the difference between places of contacts will be a PROBLEM?

Sorry for maybe-a-sillly question but I need to be sure))

You can see in the picture the threaded collars that retain the HT leads.

ok. I will solve it. good luck

[Madb]

the number " 401341688099 " needs to be entered into the site called Eblag. doing a seach on google won't show. seach on Eblag. ok?

[Almaty_kz]

I will try. Thanx pal

[Madb]

the site is that big online auction site. oss changes some words on here for fun.  . best of luck.  hopefully you'll be running again soon.
