I like the standard 'non-dial' lights myself.less stuff to get screwed up and easier to check total advance, IMO. One to hold the light, one to turn the dial and one to work the throttle. But it takes 3 hands to do it that way if youre by yourself. I don't want to spend tons of cash on this so interested in these cheaper brands. You can also use it the same way to check mechanical advance by just revving the engine. Also looking at items such as the P8000 with the advance knob, is this a useful feature over the cheaper lights with no dial/rpm read out? Do i need an RPM read out, advance knob or just plane cheap timing light? The Capri has a Rev counter but the Escort does not. I'm looking for a timing light to tune my 1979 Capri (sierra electronic ignition) and 1985 Escort mk3 (on Points). Do not forget to remove all your tools from the engine when you are finished.īe careful to keep the timing light's wires away from moving parts in the engine bay.Hey all, rather than starting a new thread i thought id ask here. Use some type of fender cover so you do not scratch the paint. Turn off your engine, replace the vacuum advance hose, and disconnect the timing light. After re-tightening this fastener, check your timing again to make sure - tightening the distributor may change your timing. Once the timing is correct, re-tighten the distributor hold-down clamp bolt, making sure you do not move the distributor. Continue doing this until the pointer is pointing at the correct degree point as required. Then, check again with your timing light. If it is farther away from the marks, then move the distributor in the opposite direction. Rotate the distributor slightly, then aim your timing light back at the timing marks again. How does it work In order to do this, we need to have a timing mark (let’s use 0 degrees for this example) on the spinning part of a harmonic balancer or cam gear as well as a fixed mark on the engine or a backing plate. Start the engine and adjust the idle to the specified rpm. A stroboscopic or timing light is a tool used to determine at exactly what angle a spark event is occurring. Only loosen it enough so that you can turn the distributor body with some resistance, not enough so that it's loose. Loosen the distributor hold-down clamp by turning its bolt counterclockwise. If it is not, turn the engine off and proceed to the next step to adjust your timing. If the pointer is pointing at the correct mark, you do not need to adjust your timing. Because of this, the timing marks will appear to be standing still. Aim the timing light at the timing marksĪim the timing light at the timing marks, and press the button on the light. Then, on the side of the distributor, disconnect the rubber hose from the vacuum advance and put a piece of duct tape on the end of the hose to seal it off. If you want, you can use some chalk to mark the timing marks to make them more visible. Now, your timing marks will have a line labeled "0" with marks above and below it, and depending on which way the wheel rotates, you will see the lines before the "0" (BTDC), or after the "0" (ATDC). There is also an "ATDC." "Before Top Dead Center" and "After Top Dead Center" - top dead center is the point where the piston reaches the highest point in the cylinder and that is when the compression is the greatest. As you can see, it also says something about "BTDC" for this Ford. All this means is that you want to line up the pointer on the timing light with the 6° timing mark when the engine is idling in gear at 550 rpm. For example, a 1969 Ford 429, it's 6 Degrees BTDC 550 rpm in drive gear - with automatic trans. Your auto's spec or emissions placard sheet should tell you what your timing degree should be. Look to the auto's spec or emissions placard sheet Rotate the pulley, if necessary, so that you can see the mark. Locate the timing marks near the lower crankshaft pulley, and the mark on the pulley itself. Clamp the largest clipĬlamp the largest clip (the one with the thickest insulation) around the No. Clamp the black clipĬlamp the black clip to the negative terminal of your car battery. Clamp the red clip on the timing light to the positive terminal of your car battery.
