28HP Johnson Electrical Problem

[jamesj]

I have an electrical problem on a 28hp johnson(1991)that prevents it from starting. The starter motor will not run when key is turned. When i turn the key i get an audible click in the solonoid. At first i thought the starter might be bad so i hooked up a portable battery pack directly to the starter and it fired up fine with no hesitation. Then i thought it has to be the solonoid, so i replaced that and still have the same problem. Can the problem have something to do with the starter switch or nuetral safety switch? I dont know much about the wiring in the switches and not sure how to check to see if this is cause of the problem.<br />thanks<br />james

Hey jamesj, Check your Battery connections, make sure they are clean and not corroded. Also check the Battery.

Hey, James.<br /><br />I agree with Shooter. You have a low resistance "open" in one of your connections in the high current circuit. <br /><br />Battery connections, connections to the solenoid and the block from the battery. It also could be a badly corroded terminal on the wires themselves.<br /><br />Take them off, clean them well and reinstall.<br /><br />Let us know what you find.

jamesj,<br /><br />Ditto the others. You can eliminate your key switch and nuetral safety switch because you are getting power to the solonoid. Problems with either one of those would stop that.<br /><br />Poor connections or a weak battery are the likely culprits.
