I was hoping some knowledgable person could help me out with this one. I'm replacing the regulator/rectifier on my 96 Johnson 70 HP 2-stroke. The new regulator I picked up has 1 less wire than the original. According to the wiring diagrams, this missing purple wire connects to the VRO2 pump and the MWS wiring harness. Does anyone know why the new one is missing this wire? Should I be concerned? Thanks.

I would be concerned.... I would contact your OMC Dealer and ask them why.... It just doesn't sound correct to me....

Purple wire is Key Switch "ON".....

Although parts do change and are updated from time to time, I would definitely question this one....

I contacted the dealer today, and they said that Johnson removed the purple wire. This wire was used for sensing battery voltage. However, the red wire already there can do that so they got rid of the purple one.

There you go.....
Now you know for sure..
Parts do change and are updated from time to time... They find better (hopefully) ways of doing things to improve the performance and the product.

Just curious...why did you need to replace the rectifier/regulator, and how did you know you needed to?
My Montauk has a 1998 70 Johnson and always curious what I need to watch for. Mine is perfect.

First, the tachometer wasn't working. Then I noticed my batteries were dead a day after they were charged without any use. I opened up the engine and the regulator was pretty warm. So it was drawing power and that pretty much suggested that the regulator/rectifier was broken.

Assistance please: as an engine novice with no fear going in and digging around, i may also have some regulator issues on my '90 Johnny 70 hp.

Question #1: (embarrassed) where might i find the regulator? Starboard rear of motor? please describe appearance.

Issue: My depthfinder is directly wired to the starter battery, i.e. not through the fuse box (this i will rectify soon). On occasion, particularly after long runs at speed, the depthfinder will not work and a self -diagnosis reveals "high voltage shutdown" and measures from 16.5-17 volts.

I assume my 12V battery should not be delivering this voltage, correct?

Should I:

1. simply wire my depthfinder through the fuse box and no longer concern myself or

2. believe that Johnny's regulator is not operating properly.

thanks in advance.
