bruce it seems that you are not getting charged fast enough,like a low amp charger. or you have too much voltage drop to the starter

Just to clarify I am not having problems with the new car just do not want to run with out alternator unless I have no other choice.

Thank you for the bridge rectifier, I did not know what it was. Those little Shogun alternators are not much but it may help. Better than nothing and even a mini alternator will not fit any where so looks like it may be my only choice.

The Shogun "regulator" is actually just a bridge rectifier. It came with a 25 amp rectifier, but you can put a higher rated one on there. I have a 40 amp rectifier on mine. Not that it will cause the "dynamo" to put out more current, it is just a higher rated unit that would be a little stronger. Listed below is the 25 amp rectifier that you can order from Amazon. You just need to make sure you connect it properly. 2 posts show the AC sinewave and the other posts are marked + and -. And you can use it on a 16 volt battery.

Thank you, is this the same thing?

If so I will buy it and have a few spares for same price.

Yes, those should work just fine. Please make sure you mount it to something that will not conduct heat to it . It should be mounted somewhere that will allow for heat transfer from the rectifier to the mounting surface. Those rectifiers do get hot. You should also use heat sink paste on the mounting surface when you bolt it down.

Also, Shogun recommends that the output of the rectifier be wired directly to the battery. Not a junction point for the battery. The battery is what buffers or controls the voltage level, so you really need the rectifier connected straight to it.

Thank you! I will order them and probably use the wimpy Shogun alternator. So do you happen to have the old Shogun instructions or wiring?

I will check if I still have the original instructions. But it was pretty simple for the wiring. The original "dynamo" had a 2 wire connector and the kit came with a short pigtail connector with 2 wires. The connectors would fit together and the 2 wires would be connected to the rectifier on the "AC" or sinewave terminals (they should be diagonal from each other. The other 2 terminals on the rectifier are labeled + and -. Those need to connect directly to the battery terminals using at least a 12 or 10 gauge wire.

As far as mounting the "dynamo", I would NOT recommend mounting it so that it runs against the harmonic dampener, that is if it still has the ribbed belt glued around the bell. I had to fabricate a mounting block to move the "dynamo" mount out further from the block so that I could use a short belt to turn the "dynamo" bell.

I was going to mount it directly under the balancer and use a short belt but the belts will not line up. Spent much of the day trying to find a way to make it work. Just not going to happen.

Once again Thank you for your help. We tried.

Since you have the room for an Optima, and reserve is a concern on a 16v battery, I would recommend going with 2 Go Lithium batteries. Two of them together is nearly the identical size to an Optima battery, and they're only 9 lbs each.
I have been running two 16v Go Lithium's and no alternator for three years, and no hint of an issue. Yes, they are pricey, but guys are getting 8-10 years out of them. Pro rated out, they're not a bad price for a very high quality battery.

I am a dealer, so feel free to call me with any questions you may have.

x2 and these batteries are rebuildlble not desposables.

While I have lot less electrical requirement than most here. Data logger,sle,one fan and primer pump and starter,
My 16v does a great job of cranking faster and more times than the 12 volt I had in caqr originally. I have cranked car I know dozen times when firs got going good just tuning in fuel system. Lots of cranking till got primer worked out, I
I did have one go bad but was after long day of cranking issues and a few floodings to the point of hydraulicing and locking up putting huge strain on starter and battery.
