I have a new SH 775 rectifier on order. I have tried to find suitable plugs to fit it to my wiring without success. Eastern Beaver does not list one.

Does anyone have source and or part number?
 
Thanks gearhead-can you point me at him? Nothing on ebay I could find just now.

Not specifically, no. But these are the connectors. I ordered the FH012/010 Connectors with 18" Leads - all pre-built and great quality.

It's confusing because Jim doesn't specifically list the SH-775, and when I emailed him to see if the FH012 connectors would work, he said he wasn't sure.

I'm going to drop him a note confirming the FH012 connectors work very nicely for the SH-775
 
Another option is to use crimp on spade terminals. After installing them into the R/R male spades, fill up the extra space in the cavity with low acid, electrical safe RTV. Cheap and secure. Also, no bulky connectors which make routing the wires more difficult. I was a little sloppy with the RTV application on this install, but you get the idea. Oh, and no way the R/R would have fit into the stock location with those plastic harness shells installed.

Thanks everyone. It is a little confusing when the thing is not listed by name.

I am always impressed with how fast answers appear on this site. Thanks!

Hi Mac,
It sounds like you found what you are looking for, but I got the pre-assembled kit from http://roadstercycle.com/

It was $45 and it was already soldered and shrink wrapped, with a self-resetting breaker. It would likely have been cheaper to piece it together myself, but I was up and running much more quickly than if I had been forced to put my solder skills to the test.

That's a handy link.

Someone should mention that the terminals that come with the kits are 'open barrel', and require a crimping tool specifically for that purpose. Anything else is just troglodyte.

Personally, I love open barrel, but it takes a good tool and a little practice. Nothing wrong with letting someone else handle it -- which is slowly becoming my standard motto anymore.
 
Yes, it's a nice piece of work, and so is the harness from Eastern Beaver, but I tend to end up modifying their harness so much, I may as well do it all myself from the beginning. :D

Not to mention the fact that it saves me $20-45 each time. :-\\\

Got the new SH 775 BA today. I am fabbing an aluminum mounting plate, because I need to rotate it 90 degress to get it to fit.

The wiring looks straightforward, with one question- in the double plug, which is ground and which is power?
 
I just observed my new SH 77r RR with my multimeter. At 4500 rpm it charges at 14.5 volts. Turning off the headlight, the voltage drops to 12.9. It responds to the load on it, and only provides enough power to cover the load. Turning the headlight back on, the voltage returns to 14.5.

This is how it is supposed to work, right?

Could be but I would not expect that. If the R/R is expected to regulate at 14.5V it should regulate at 14.5V regardless of the lights being on of off. The only time it cant achieve 14.5 is if there is in sufficient voltage coming from the stator. Are you sure the 12.9V is at 4000 RPM with the lights off?
 
I have been using the bike with its new electricals for a month. 78 GS1000C.

I get 14.4 volts at 4500 rpm with the headlight off. Headlight on, it drops to around 13 volts. I have a very bright halogen bulb, which accounts for some of this. Does the Sh 775 RR behave like it should, or is there something else going on. From what I read, shouldn't it maintain a steady 14.4 volts?

Time to review the headlight circuit, and install a relay, and consider a new bulb with less draw. How much difference will a relay make?

The other issue is I have twice blown the old 15 amp glass tube fuse. This was on a semi melted but resoldered set of clips. I have replaced it with a modern inline fuse, so far no problems.

On the charger the battery goes to 13.3 volts, then gradually drops to 12.8 or so where it stabilises. Over 4 days storage it has dropped to 12.3. Is this a sign of a battery problem?

Did you wire the stator directly into the R/R like conventional forum wisdom dictates? Did you check for resistance drop, and subsequent voltage loss, in the R/R power output circuit on the way to the battery? Assuming yes to both these, then voltage falling to 13 volts with the headlamp on is a sign of a weak stator.
 
Thanks Steve, and Nessism. I will check connections and run the tests again. This is a brand new Rick's stator, and should not be faulty.Stator wired straight into the battery as recommended here, and diligently followed.
