Re: Reverse-mount 12V alternator

I still deal with flame cut stuff occasionally when we have really thick/large parts. Even then, the cut quality is so nice! Flame cutting has come a long way! To your note, I plan to run a ground from the back of the alternator to either body or engine. I thought about masking contact areas, but fi...

Re: Reverse-mount 12V alternator

The bracket is back from manufacturing! https://i.imgur.com/3xlZkzE.jpg Super pleased with the results, just need to weld it up and send it for powdercoating. I decided to run a quick BOM to see how my cost looked versus the +$1000 version from Sweden and I think I'm doing pretty good! Just need to ...

Re: Reverse-mount 12V alternator

So 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? The 12v and 24v systems will ...

Re: Reverse-mount 12V alternator

First revision looks on the money! I'm going to make one tiny adjustment and then hit go on the metal versions! Going to throw together a bill of materials here soon to get a cost estimate. I'm figuring I'm well under the $1k+ being asked in Sweden... https://uploads.tapatalk-cdn.com/20190725/013f78...

Re: Reverse-mount 12V alternator

Sorry for the slight delay, I got a little preoccupied helping a friend install a 3" lift... for his Miata. Really awesome project!! https://i.imgur.com/NdcPc0g.jpg I had a bunch of trouble getting the idler how I wanted it and everything and keeping cost down, but I finally got it worked out and I'...

Re: Reverse-mount 12V alternator

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! Dan 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, bu...

Re: Reverse-mount 12V alternator

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. 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 betwee...

Yeah exactly! Whatever you can find in a 10SI case, it shall bolt up.

Re: Reverse-mount 12V alternator

I can understand if you have a lot of 12v items in the truck but when it comes to winches, 24v ones are available from most brands and work better than a 12v winch as well. That was actually plan A, but I found the cost of 24v winches was about equal to doing this project and buying a 12v winch. No...

Yeah! I just wanted a dedicated 12v system for running a winch and whatever else. I could run a converter but I feel like this is a little more robust and provides a lot more amperage.

Re: Reverse-mount 12V alternator

So the first model of the bracket came in today. For hand measurements, it came out awesome. Basic fit was solid. I need to adjust the belt alignment and drop the alt a little to better clear the doghouse. That will affect belt engagement so I will likely add an idler. I have a lot of confidence thi...

The original intent was to add a 12V alternator, but you can get a 24V alternator in a 10SI housing, so either could be done.

Re: Reverse-mount 12V alternator

kdiqq As far as I can tell your design is based on a single laser cut part, that will be folded and tack welded in the following steps. What is the material you intend to use ? You are pretty much correct! I intend to waterjet instead of laser, just because it's cheaper, but the finished product is...

Re: Reverse-mount 12V alternator

kdiqq an excellent design ! which alternator have you decided to use ? I guess they have more or less standard housing sizes, so I could find a suitable one from eg. Bosch .... Thank you! You are correct, the housing is known as 10SI and there are tons of options. I wouldn't run higher than 90A tho...

Re: Reverse-mount 12V alternator

Please keep us posted on testing and let us know if you decide to do any production. Looks real cool! MM For sure! I'd love to be able to give back to the community. If I can get through a couple of weeks of use without drama and finalize my bill of materials, I'd be happy to run a batch of them. S...
