No, one is electrical wether it be a relay or a contact or just a switch. And the transmission is totally mechanical.
TCS stands for "transmission controlled spark". It is a switch mounted to the top cover of Jeep CJ7 T150 manual transmissions that is used by the engine computer to know when the vehicle is in top gear. The engine control computer then advances the engine timing for better fuel economy.
That is the electrical switch that is bolted to the driver's side of the transmission where your shift cable hooks to it.
Possibly a faulty brake switch (or faulty clutch switch, if you have a manual transmission).
In the front of the motor by the transmission dipstick. This is where your spark plugs from the engine go.
The kill switch interupts the spark to the spark plug and stops the eingine.
It's on the end of the gearshift lever ( P R N etc. )
If you are seeing a spark then the switch should be changed out right away. The spark is created by bad contacts within the switch its self. These bad contacts will create heat and eventually destroy the switch. Make sure that the rating of the switch is greater than the load that is connected to it. The only time a switch might draw an arc is when it is opened but it should never arc when closing. Yes there should be a spark when a switch is put on.
If this is an automatic transmission, the switch is located on the driver side of the transmission housing where the linkage plugs into the transmission. If it is a manual transmission the clutch safety switch is located near the top of the clutch pedal.
Neutral safety switch is only on a manual transmission. The switch is in the upper rear of the transmission case.
The switch for the backup light switch for an automatic transmission is located on the transmission where the shifting cable enters the transmission (The side of the transmission closest to the radiator),how about for the manual trans mission models?
near the spark plug. some engines have lever that touch the spark plug ,others have a grounded switch
