you have to tap into the coil wires the negative wire on the coil plug.
you can wireit directly to the coil... check for the positive and negative wires or there is also a place in your distributor.......
The COIL HAS A POSITIVE AND A NEGATIVE TERMINAL. If you look at the top of the coil, it is generally marked + and - on the top.
If its a dual coil run positive to positive and negative to negative.
remove resistor from loop positive to positive terminal neg to neg
how do you put spark wires in the right place on the coil pack on a 1995 Chevy cavalier2.2 frank
You should hook up the wires for a tach on a 1985 Chevrolet s10 blazer to the negative side of the coil. You should be sure to identify the positive and negative sides of the coil.Ê
Not sure about your specific model, but the negative side goes to ground, the positive side goes to the wire that is hot when your key is turned to the on position. You can tell the positive side of the coil as it will have continuity between both the primary and secondary sides of the circuit. (The negative terminal being the primary and the coil wire going to the distibutor being the secondary.)
To much resistance in the spark plug wires, replace the spark plug wires.
take the wires off the + and - side of the coil, pull the coil wire out of the coil, unbolt the coil from the manifold, to install just reverse directions.
if the coil is on the distributor cap,remove cover then disconnect wires from the coil and remove coil. if coil is on engine then loosen the bolt and remove from coil mount
There are two ways that you can do this: 1.From the ECU Cable, that's on the GMC, looking from the bottom of the wire harness clip, the 4th wire from the left bottom series of wires for negative, and the positive on the 2nd wire from the right hand side top series of wires. 2. attach wires from the tach from the negative side of the main branch of the coil pack positive wire, and negative to the negative wire. Then after that's done it should work, depending if you need a power supply from battery or turn-key acc on wire.
here is a diagram
under the coil packs and the coil packs are connected to the spark plug wires
Generally 4 wires: red= switched positive( positive only when car is on), black= ground, generally yellow= tap into a dashlight, generally green = negative on coil.
Depending on which coil you're speaking of, it could be marked: ( - ), NEG, or TACH.
Check your Ground (negative) cable to the block. Also check the grounding of the coil to the block.
no distributor or spark plug wires its a coil pack on the top of the engine.
The ignition module is located under the coil pack. Follow the spark plug wires to find the coil.
No, just the positive side is hot.
THE COIL ON A 1977 CHEVY TRUCKIS IN THE DISTRIBUTOR CAP. TAKE THE PLUG WIRES AND HOLD DOWN RING OFFOF THE CAP TO EXPOSE THE COIL. WEDGEMAN
negative side of the coil
disconnect wires and label them,each coil has its own screws holding it to plate,take out scews,pull coil straight up do not bend the coil tangs at mounting of coil. Do this for each coil! HOPE THIS HELPS!
Should be 9 larger wires (1 to each spark plug and 1 to the coil) Should also be a connector (small wire that leads to the negative side of the coil)
