Hey everyone,
I got a fixer-upper '71 Ski-Twin 40153G and I'm eager to get it running again. I've restored smaller & older engines before, but this one has some features with which I'm not too familiar. Let's begin with the charging generator.
The seller told me that he always "pull-started" the engine...in fact he didn't even know it was an electric start engine when he sold it to me! I was happy to discover that the starter motor & solenoid are in tact (although not yet verified to be working) *AND* there's a charging generator, albeit not connected to anything.
Question 1: Is this a generator or an alternator? Based on age, I'm suspecting "generator", but don't want to assume. I purchased a service manual, and I'm disappointed to see that there's zero mention of this feature; likewise, the parts book makes no mention either. So what do I have? Was this an Evinrude option? Or was this an aftermarket add-on?
Question 2: Regulator....there's none present. Nor can I find much info about what Evinrude used, what the replacement is, etc. Suspecting that this is a generator (not an alternator), I'm going to need something.....so what do I use? On eBay, I see all sorts of NOS regulators for old cars, so I'm wondering if I can use one of those. Guidance is appreciated!
Question 3: the electrical harness in the engine is a mess, but the plug (black, 5 pins) is in decent condition. I'm an electrical engineer, so making a new harness and re-using this plug should be easy, but I'll be darned if I can source the mating female receptacle. I don't need a complete harness....just the receptacle. Can't find it or a part number for it.....only a part number for the entire harness (discontinued).
So let's start there, although I'm sure more questions will come up!
Thanks for your help and support,
Mark
