Typically, when setting the timing initially, you would want the rotor to point to the #1 wire on the cap.
That depends on the exact model/make of car.
The rotor button is inside the distributor cap.
A "rotor button" is located under the distributor cap (in an older vehicle) prior to the use of "Coil on Plug" or electronic type of ignition systems. As the distributor rotates the rotor (which is attached to the distributor shaft) has only one contact point is directed to the spark plug to be "fired"
Rotor buttons are inside a distributor.
Turn the engine over until the #1 piston is at top dead center (TDC) on the compression stroke. The rotor will then be pointing to the # 1 plug connection.
rotor will point to #1 at TDC.
First of all, you cant point a rotor button. Rotor buttons are mounted inside the distributor cap. You can point the rotor. The rotor is whats mounted on the distributor shaft and turns with the shaft. Remove the #1 spark plug. Disable ignition so engine doesnt start. With a helper bumping the starter, put your finger over the #1 spark plug hole and have helper bump starter until you feel air blowing by your finger. Now, using a large wrench or socket, manually turn the crankshaft and line up the timing marks to TDC. Your rotor should be pointing directly at TDC on cylinder #1. transman
The rotor only fits one way on to the distributor shaft.
rotor button is the little gadget inside distributer cap attached to the distributor shaft this spins when engine is turning over, distributing the spark to each plug at the right time
Most rotors turn clockwise.
Broken rotor button.
They only go on one way.
Under the distributor cap.
Remove the distributor cap and pull the rotor off. Sometimes the rust to the shaft so if you are careful you can use a screw driver and pry it off. It the rotor button breaks, they are cheap enough.
if you have the number four cyl on compression stroke you would want the rotor pointed at cyl 4
The rotor lifts it straight up, that is the whole point of having a rotor
if your looking for rotor button in ignition it does not have one, it is electronic computer controled spark thru cam shaft and crankshaft sensors. I your talking 4 x4 rotor lock button for 4 wheel drive it does not have one either, the 4 x4 shifter does that when you engage the 4 x 4. If your talking about something else please give more info.
under the distributor cap and rotor button
If it has a distributor, check the rotor button for a burn mark underneath. The high energy coil will sometimes burn a hole through it causing the fire to ground. Replace rotor button.
TDC on the compression stroke for number one cylinder, looking from the front, the rotor should be pointing to the 5:00 o'clock to 5:30 position on the cap.
rotor should point to cylinder #1
There is two screews that hold the cap on ,remove them. Then just pull the rotor up and off. It will only go on 1 way. Transfur wires to new cap while keeping them in order.
