weird electrical problem

i checked the rr and it seems fine, i get good continuity everywhere except a to e is about 5 ohms. can someone tell me what the pick up coil is and where i can find it.

Hi Ice,

If you are serious about this,

The pick up coil is part of the ignition low Voltage circuit. Like points in older days.

Do you have an oscilloscope? and the knowledge to use it?

If yes, I can give some more tips.
 
The pickups are under the right hand engine cover. I'm a 4th year electrical engineering student and can not get a proper resistance reading from them so don't be alarmed unless you have an infinite resistance (or perhaps no resistance at all)...the bike still works.

Bikebandit.com has great schematics for bikes if you are ever in a pinch during the middle of the night. If your bike isn't listed just look up the same years 1100, the 4 cylinders are all the same for parts locations.

You should be getting 50-70 ohms probing A & E.

Hi Steve,

You still have to measure the pick up coils signal, if you want to know if they are working, as they should, and the best way to do that is to use an oscilloscope.

Old goat analog technique. :wink:
 
With Nortel laying off 50,000 employees in town I can pick up scopes with hundreds of channels for 20% of what they paid for it new two years ago. Spectrum and Network analzyers and everything else for next to nothing...I wish I was starting a business. :( If it were General Motors they would have everything destroyed so that their competitors wouldn't get a leg up.

my physics professor has an osciliscope, my pick ups are routed directly into the small connector of the ignitor except i have 4 wires going into the small one and not three like it says i should. i know i should be getting 50-70 ohms from a and e but i get 5 ohms, does that mean it's broken?

You don't need more than one channel for a Suzi, and no more than max. as a couple of hundred Hertz (12.500 rpm absolute max.).

It's only a question of measuring the low voltage pulse at the ignition coil to see if the pick up coils is working as it should.

If you measure as the the starter revs. you don't need more than a couple of Herz. :wink:

So, you go for the scope test?
 
yea sure but not till monday cuz thats when i have class, i need to know about that other stuff, whether it's normal.

OK, no fooling around....

Connect the scope AT THE LOW VOLTAGE side on one of the ignition coils + side.

If the pick up coils are OK, you should be able to see a square signal on the scope that frequency matches the revs. of the bike.

If the bike does not start, the signal is like 300 rpm divided to 60 = like 5 Hz.

If you can't see that signal, like only DC-Voltage, look into the pick-up coils, if you can see the signal as described look on the high Voltage side if there is any spark at all (maybe you can start with the spark check, if you havn't done that)
 
5 ohms isn't much resistance compared to 50-70. You'll have to get your answer from one of the engineers though. If it were a transistorized amp that had that big of a difference in what it was supposed to have in resistance from a speaker, and what it was actually presented with, the amp would probably clip and shut down.
 
well right now as i said in a different post i removed the whole wiring harness but before yet it would not start at all

Do you have a spark on all plugs?

Are you able to do testing now?
 
i have not been able to do the testing of the plugs yet because my 5/8 plug socket doesn't fit and i have 0$ to get a deep socket set.

Ok, the 18mm socket is normally included in the bikes std. tool set, maybe you can borrow one.

Make a new post if you want to know something else.
 
can someone help me with r/r problem, too low resistance on A to E

If the GS500 has the same r/r as the GS 1150...

I think so, if not please tell me somebody.

You should have five connectors on the r/r from the left to the right, the first is DC ground -, the next thre are the AC-wires from the stator and the last is DC +.

If I understod you correct, you have too low resistance between DC + and DC -.

What readings do you have? both directions the same value?

According to my spec. the reading should be endless one way and 50-200 Ohms the other way.

Do you trust your ohm-meter?
 
yea i trust the ohmeter. the reason why i think my r/r is broken is cuz i rerigged the wiring system and it still doesn't work.
