I have 1977 gL1000 that I am refurbishing. Where is this 7 volt regulator that is mentioned?

It's along with the other electronics underneath the cover of the left side of the false tank.

Not sure what your issue is, but the 1977 also has 4 silicone diodes that are prone to failure with age. So if all your gauges are off, then the 7 Volt regulator needs attention but if there is for instance a neutral light that is lit when not expected it could be a diode issue.

I think i am having an issuse with the 7 volt regulator, my temp guage will go all the way to the H and the fuel guage is all over the place. The neutral light is always on, when i am in neutral it gets brighter.
The other thing is my paper work says it a 77 but the frame is for a 78 and it is wired like the 78. Not sure where the 7 volt regulater is.

That definitely sounds like the 7 volt regulator. It is located under the maintenance panel on the left side of the false tank. See: 7 Volt Regulator

Look at the regulator on your bike now. Compare the connectors to the picture below:

If yours has connectors like the top one, it's a type "A" for 77. If it has connectors like the middle one, it's a type "B" for 78-79.

I have a '77 and it's not like any of the ones pictured above. Here's a pic of one like mine and in countersunk into the frame.

Here's cheapest one on eBad right now.http://www.ebay.com/itm/1976-76-HONDA-G ... 66&vxp=mtr

If it has the three tabs like the one in your picture, it is a Type A, for 1975-1977. The reason yours doesn't look like one of the three in the picture I posted is because the three in the picture I posted are aftermarket replacements that I build and sell: Goldwing 7 Volt Regulator. The original Honda 7 volt regulators are well known to fail after a number of years of use, that's why I created the replacements that you see in the picture I posted. I originally designed and built it because my own regulator failed. When I mentioned publicly that I had done so, I had a sudden huge demand from people to make one for them as well - so I started making them (and continue to make them today, many years later).

You can buy that used replacement OEM on eBay, but keep in mind that you will be buying a part that is almost 40 years old, and is a known common failure item. Plan to be changing it again in the near future. :)

Wish I had known that before I bought my "old" replacement last week. I guess that's what I get for being a newbie! Live and learn. New is better. Mine would have been the middle one with the three spade connectors. Do yours fit into the same cut-out hole or do you mount in another method? Thanks
