Well, kind of.... Putting a wire from the solenoid to the alternator will bypass the ammeter, but it will bypass other stuff as well. If you look up at Bob P.'s post with the picture of the shunt wire he has it as just going from one post of the ammeter gauge to the other post of the ammeter gauge -- that's like a three inch wire. That's a true shunt wire. I prefer to run a wire from wherever the first convenient connection is on each side of the ammeter which, for me, happens to be a circuit breaker connection and a fuse box connection both on the engine side of the firewall. But that's on an ERA, every manufacturer is different. OTOH, if my ammeter was really, super-duper easy to get to, like being right out in front of my face, so that I didn't even have to bend my back, much less crawl under the dash like an eel, then all I would have done is exactly what Bob's image shows.
