kghost, hi there my name is drew w' and i have a 1988 3.7l mercruiser 165hp 224cid 4cyl engine and i just installed the pertronix 1146a ignitor kit along with the 40611 "epoxy filled" 3 ohm coil on the boat today...now with wiring it up the black wire for the module goes to - side on coil, done....the red wire from the module goes to + side of coil, done....now the old coil is 1.5 ohms and has a resistor wire going to the coil with purple and purple yellow both tied in together with a terminal, i took them off together and have not cut anything on them and wont if i dont have to as i have read plenty of these forums and i should just tape it up and secure it for future date if i go back to points again....okay the grey or tan wire was my tach wire and that went to - side of coil and put the nut on both it and the black from the module, done..........now my main question i have is there are two wires attached with one terminal going to the choke, one was flimsyer than the other and i put my digital voltmeters blk lead to engine ground and red lead i poked both wires while my grandpa turned the key to on position without starting it and i received 12volts on both those wires while keeping the black touched to eng ground....okay and the pertronix kit came with instruction to verify if i indeed had a resistor wire so i followed it only after i took the points out and installed the new system and one of those wires the flimsy one got hot so i thought it must be because it was resisted and i added a 3 ohm coil to do the test and was way too much amperage so that must be the one i dont want, so i took the sheath off the other one the stiffer one and soldered a new 10 awg wire to it and ran that to + side of coil.........woom started right up and set the timing just to be sure to what the manual calls for 8 btdc and all is well .... let her run a bit like ten minutes and after killing it i just happen to touch the coil itself and man she was hot, now remember its the epoxy filled one and we did away with the water cooled voltage regulator for a aftermarket alternator conv kit off ebay and all that is fine and dandy but the coil bracket is right next to the valve cover and that area gets hot.......after reading this did i wire it up correctly.......oh the splice is bout three inches from the choke itself or three inches down from that little plastic thingy that attaches to the choke.... i will get u a pic or a youtube vid tomorrow .......thanks for all your help and esp your time.....cheers.........DREW W'
