johnson 115 v4. ignition problems

[alcfer]

Hello, I thing that my old engine has an ignition problem because sometimes and suddenly loses the power as if it run only in 2 or 3 cilinders.<br /><br />I have the clymer manual and i'd like to check the ignition sistem. I need to get the jumper leads to check the sistem, but i don't know where i only have found the amphenol pins but i can't obtain the waterproof connectors and tubbing to fabricate the jumper leads.<br /><br />Do you somebody knows where i can buy these pieces.<br /><br />Many Thanks<br /><br />Fernando

Fernando - You don't need anything special for jumper leads to use on a boat. I made a set out of stereo speaker wire with alligator clips (one red + and one black -) on each end. Make sure that you have both reds on the same wire. I made it about 15' long so that I could go from about anywhere to about anywhere. You can get the wire and clips from most hardware, stereo or other shops that sell electrical supplies.

Many thanks for your help.<br />I'll try to make a set according to your idea.<br /><br />Only one think that i don´t understand.<br /><br />?How do you connect the multimeter's lead when the jumper lead is connected with your wire speaker set¿. In the manual that I have, said that you must use the tubing connected in one end.<br /><br />Thanks in advance
