XJ650 Seca Turbo. Safety start problems

I just got a Seca urbo 1982. I can start the engine no mater what including with the side stand down and the engine in gear. I found the start cutoff relay diode (inside) cutoff. Looking at the diagram, I should not be able to start the bike in some circumstances. Any ideas? I am expecting a new rel but I do not think it is going to fix the prole. Also, the neutral light never goes on.

 

could be the side stand relay has been removed or side stand switch shorted together to bypas that.the cable from side stand and neutral switch coming up to the harness connector may have been unplugged.
also the black white wire connected to the tci box could have been disconnected its a bullet connector in a rubber sleeve near the box on the pick up coil connector
does your clutch lever have the safety switch and wires connected to it? it may also be shorted to gether to bypass switch

 

Thanks for helping out. Everything looks ok from the outside. (no wires disconnected or jumped..etc. The side stand relay is connected and I have replaced it with no results. I was looking for the silver bullet (like some other person with the same experience that found the solution) but I guess I will have to start troubleshooting wire by wire. I am also awaiting the new start cutoff relay . Lets see what happens after I install it. THX again. I am laso going to check if the ground connector on the relay ( the one that goes to the neutral switch and the side stand switch is shorted to ground. That is another way that would energized (on) the start cutoff relay as soon as I turn the ignition switch on.

 

mostly the opisite problem the safety switches keep members from starting the bike

 

Well. I troubleshoot the problem and I found out that previous owner bypassed every safety feature there is...... by grounding the wire for activation of the relay. I fixed that but now the problem I still have is that the neutral switch does not appear to work. The light is off. I purchased a new switch but I CANNOT FIND WHERE THE SWITCH IS. Remember, this is a 1982 XJ650 Seca Turbo with final drive. I have read in some blogs that it can be where the chain sprocket is, under the cover but I have no chain. THX for any help. The pic in the manual is very confusing.

 

Before you dig in to changing the switch (it's in a recessed area of the oil pan, adjacent to the shift lever) make sure that the bulb is good, and ground the wire for the switch to the engine case. If the light comes on then you can suspect that the switch is faulty. Test the switch by connecting an ohm-meter to the screw that comes out of the end of the switch, and to the engine case. When you shift into neutral there should be continuity if the switch is working. Most of the time the problem is that the switch best gummed up with sludge and can't move to make contact with the gear selector in order to complete the circuit. You can bypass the switch by grounding the switch wire, and run the engine with sea foam to clear out any sludge. If the switch dosen't work after all of that, then you can work on replacing it (it is a royal PITA to get to because of its location in relation to the frame).

 

Thx for helping!. I saw a wire coming from the area you mention but I thought it was the oil level sensor. Does the neutral switch has a cover with two screws, before you get to the wire and the screw holding it?

 

Oil level sensor is right in the bottom of the pan..... The neutral safety switch is basically up along the side of the pan, sandwiched between the pan and the frame rail , and probably hidden behind some exhaust stuff ( as well as covered in dirt/grease/grime).

I'd suspect your lightbulb before the switch

 

I went to Ebay, lok for the oil pan and.....there it is!! I took a pic of the neutral switch. Finally I located the thing!,As far as the problem...if it werre the light the switch still would prevent (or allow) to start the engine. The switch act as it was transferred (on gear) so the light does not have to be on. Any way I will look for continuity to ground when in neutral and see what happens. Probably I will live without it. THX again

 

Well, well, well. I looked at the oil pan following the picI have and found out that the so called "neutral switch" is the oil drain bolt. It looks like the neutral switch but it is not. Mine even has a screw in the middle of the bolt that loks just like the neutral switch but it is smaller.I confirmed with another pics of the oil pan on Ebay and I cannot find any pan showing the neutral switch or even a hole for it. I am really confused. All I can see on the oil pan is the oil level, another oil little connector with house and the oil drain bolt. Help still needed..
I will have to lay down on the floor, after elevating the bike, and stick my head and a light and follow your instructions along the pan. Saga continues.

 

The oil drain bolt is on the front of the pan under the oil filter and threads in parallel to the ground. The oil drain bolt is of a different size and does not have a screw in it. There is oil on the other side of the neutral switch, but that's not where the oil is supposed to be drained from (you should drain the oil if you plan on removing the neutral switch).

To find the recess look for the oil level sensor (See Dave's description). Bring your hand toward the lower left frame tube. Run your nadd along that tube until it is just about even with the toe-end of the shift lever. There will be a light blue wire, and a deep recess. The switch is in there.

If there was no wire connected to the screw of the bolt (the switch looks exactly like a bolt, but has a screw in the head) then your problem is that the wire is not connected to the switch.

Here's a photo of the switch:

 

Uh, that's right up there with the squishy British.....lol

 

One must always assume that my advice is peppered with the effects of beer.
