Mercury Switch Boxes

Can a Mercury Switch box part #332-7778 A1 be replaced with #332-5524A1? The only difference is one is from an 82 and one is from an 83.

I punched in both part numbers into the computer and they both are superceeded to the same new number. So I would say it will work.

Re: Mercury Switch Boxes

Thanks Trent. You told me once before to dosconnect my rectifier and try for spark. Did you mean to disconnect all the wires from the rectifier?

Re: Mercury Switch Boxes

Yes remove all wires. Also check for spark with all the sparkplugs removed.

Re: Mercury Switch Boxes

Trent I will test tonight for spark on all six. I am getting a set of used switch boxes for a great price so I guess I will just try those first. I know that is not the best method but I am no mechanic. How do I test with all plugs removed?

Re: Mercury Switch Boxes

Why would you disconnect the wires from the from the charging side of the stator. The regulator rectifier would not cause a not spark condition. The only thing that would cause a not spark conditon would be a failed stator, stop circut(black and yellow wire), or a bad switch box.

This a quote from Schmetic:<br /><br />"In some cases, a shorted rectifier can cause high magnetic flux under the flywheel and raise havoc with the charge/trigger coils. Disconnect all wires from the rectifier to see if the spark returns. If it doesn't, its not rectifier related.... " <br /><br />c/6<br /><br />Hooty

Thanks for all the help Hooty. Turned out it was my kill switch and my inability to check it out.

Re: Mercury Switch Boxes
