2000 j25tessd rectifer question

[gulfcoastsurf]

all right i am going try to fix the rectifier for once and all tested it and no charge while running. how hard it it to install a new one i see on Johnson parts catalog they run about 50 dollars would you suggest having a mechanic install or should i do it myself neighbor has service manual also is there any other place i should test before purchasing the rectifier also dumb question but this motor dose have a rectifier model # j25tessd thanx and sorry if the post is poorly written just started this forum thing

If the 4 wires coming from the rectifier are connected such that they can be disconnected without removing anything else, it's just removing 2 bolts holding the rectifier to the block ... should be a 5 minute job!

Don't forget to disconnect the battery first!

great anything else that i should know i thought i heard that you should test some where in the fly wheel also but would feel to confident doing that

Re: 2000 j25tessd rectifer question

You are probably referring to testing the stator (under the flywheel) ... that's the part that sends AC current to the rectifier (to be converted to DC). To test it, you will need (at the least) the OEM Johnson/Evinrude service manual (which contains instructions for testing) and a multimeter.

If your motor is running, but just not charging the battery ... it could be that the charging coil in the stator is bad ... but the other coil that supplies a spark to the plugs is OK. Only way to know for sure which component is faulty is to troubleshoot the entire circuit.

Electric "gurus" ... please feel free to jump in and correct me if I've misstated anything!

Not a full test of the stator coils but you could check then for continuity with an Ohms meter. Should find continuity between all three yellow wires coming from the stator.
Should find approx twice the resistance between yellow and yellow blue as between yellow gray and either of the other two.
