Yeah exactly! Whatever you can find in a 10SI case, it shall bolt up.pinzi wrote:Or you could go for a second 24v alternator

There's a couple of ways to figure that out and there are a few discussions on which is best online. From what I can find, the range is somewhere between 4 and 10HP. Since I'm using a smaller 90A alternator, Id say I'm somewhere in 6HP range. You may notice that on a 90HP motor, you might not. There are always tradeoffs with pulling accessories off engine power.whitesik wrote:Not even close to an engineer here, but how does this tax the already meager HP of the motor? I think that has been a concern in past discussions.
I consulted with an electrical engineer that I work with who has built a few electric motors. He said you can try and keep the grounds split, but the alternator grounds through the case. It shouldn't be a problem. Sounds believable since there are a few guys on the military truck forums who are running dual systems with a common ground without issue.TechMOGogy wrote:Lots of post here about trying to run both 24v and 12v and issue with common ground I believe.
Others here with more knowledge than I should chime in!
The 12v and 24v systems will use a common ground. From all the other dual-voltage setups I investigated, I never saw anything about voltage ghosting. I don't imagine there will be stray voltage over ground in any scenario. The couple of electrical engineers I spoke to had zero concern with the configuration having a shared ground. If it did become an issue, the alternator can be easily isolated thru the mount via a coating. Even powdercoating would work. I plan to run it as is though. I suppose to double check, I could run an oscilloscope on the 24V ground and 12V ground and see what feedback looks like.Andre wrote: ↑Mon Jul 29, 2019 7:26 amSo how do you plan to eliminate any voltage ghosting through the alternator housing?
Will you be isolating the mount to run a direct ground and power to an auxiliary battery? Or will you have a disconnect switch on the power supply to the existing battery jumper cable?
