I am having issues with my generator so I was thinking of switching to an alternator. I have 12 volt already so will just need the brackets and the alternator.
Looking at amperage, some are 65 amp, 105, 120 etc. Is to much a problem? Can I damage any electrical with too high output?
Thanks in advance, John | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy 54John3100, the amperages listed on the alternators are their maximum output, not what they constantly put out. The internal regulated alternators are the simplest to install. Personally I prefer the three wire install rather than the single wire alternator because of the voltage sensing issue. The installation can be accomplished using some of the original wiring, as six volt wiring is twice as big as it needs to be capacity wise. I can provide more specific information when/if you decide to go that route. | | | | | Joined: Sep 2011 Posts: 305 Shop Shark | | Shop Shark Joined: Sep 2011 Posts: 305 | Thanks Bobb.
I'm having issues with the generator system and rather than spend money on trying to find the problem and then money to fix, i am taking the easier route and change to an alternator.
I knew you would have the answer.

Here is a simple link to some tests you can do. The procedure is for a 12 volt system, but the readings would be about half. http://www.netlink.net/mp/volks/htm/gen.htm

I have installed a Single wire alternator. I have seen some drawings on line to wire it up. Basically wire it from the single terminal on the alternator to the "Batt" tab on my old regulator. Is that correct?
Leave the other two from the old generator hanging or should I remove them from the regulator too?
Thanks, John | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy 54John3100, yes that sounds correct, if you don't remove the field and armature wires from the regulator then tape them up separately to insulate them. Connecting the alternator output to the "Bat" terminal of the regulator has the "Bat" terminal acting as a terminal block. This way of wiring the system will allow the rest of the electrical system to function correctly. Personally I would not use the regulator "Bat" terminal for the connection between the alternator and the factory wiring, I would remove the factory wire from the "Bat" terminal of the regulator and connect the alternator output wire to it and insulate the connection, hope that helps. | | | | | Joined: Sep 2011 Posts: 305 Shop Shark | | Shop Shark Joined: Sep 2011 Posts: 305 | So, take all the factory wires off the "Bat" of the regulator. Then run a separate 10 to 8 gauge wire from the Alt. to the "Bat" terminal on the regulator. Remove the other two so I don't have to tape them off at the Generator end.
I'm not good with electrical and I don't want to fry anything. | | |
