C.O.P.Got a little hot

[rollin thunder]

I have been having bad gas milage lately so I checked and switched my plugs today.I put a huge gap like .040 on one plug ,fired it up and it ran great .I took the plug out returned it to normal gap ,went for a spin .I noticed my tach was jumping so I pulled over to check it out.I was smelling smoke so I pulled my seat off pronto and noticed that the resistor on one of my C.O.Ps melted the seat alittle and came right off.The weir thing is the bike seems to run better but I rushed home cause I didnt want to get stranded.My question is if I take some electrical tape and wrap the wired will it be ok.It is alittle singed right now.:confused2:

Did you get your kit from Gannon?

+1...if you got your kit from Gannon...he would be the one to answer that question.

You must have had the resistor resting on the frame pinched between the frame and seat. I would think when you sat on the bike the resistor cracked and partially crumbled loosing its heat dissipation thru the resistor coating. When the resistor coating crumbled the wiring came into contact with the frame thus causing the tach to jump around. If you still have your stock coils, I would put that one back into operation until you contact Gannon and get a replacement for that one position. Thats just my theory on what happened, I may be completely wrong.

I wouldn't run the bike without the resistor because of the potential ECU damage.

He should have the updated tci box on his 93, unless that didn't change until 95.

+1, without the resistor material the tape would just melt. I would talk to Gannon to let him know what happened, I'm sure he'll work out something to get you back on the road quickly.

That is getting more common of pinching the resistor under the seat. I can get you hooked up with a replacement PM me

Thanks G

+1, I'm sure that is what happened to mine as well. I have mine routed better now so as to keep them protected and ventilated.

My resistors are placed as the picture shows where the old coils were placed.

Very nice routing I might add! If you don't mind I will use your picture on the installation manual in my next printing!

Be my guest I have done it the same way in the front after removing the front coils. Here is another picture.

I will have to do that ,cause they get real hot.The red wire into the white plug to the left connected to the square black plug gets kinda warm too .What is that?.

 

[davesax36]

Is that the main 30amp fuse? I think it's labeled on the plastic.

 

[88vmx12]

you are using the dielectric grease correct? and your connections were not corroded in the beginning?

[rollin thunder]

Correct.Ihave cleaned up all my ground connections and the wires to the battery .

Resistance creates heat. Going to be a normal part of the process. If the coils are run without resistors then there will be more spark energy available.

If there is someone willing to buy a set of unresistored wires (from gannon or me), I will give them a 2 year guarantee that it won't burn up the CDI box. I want to get someone that rides regularly a chance to disprove the CDI's are burning up because of the increased resistance. This will need to be on a bike with 90 or newer ignition (I have more of those CDI boxes).

I will also comment, The NEW ignitech units Dingy (and I) sell are able to run these standard harness adapters without resistors. So, cheaper adapters AND a better box! It can even run the Vboost so another box with potential problems eliminated!

Could you, in theory, run a bigger gap without resistors?
