I bought one of those and with the fan shroud in place (stator?) couldn't get the tool to work - I ended up loosening the alternator bolts and letting it tilt forward until I could get the belt off, then also held the belt up with a bungie cord and did the opposite to put the belt back on...

Take out the two front bolts, push down on the case and remove rear bolt, then let the alt tip forward. Easy peasey.,

Luckily, I still have the strength to pull the belt with my left hand while engaging the kickstand with a long pry bar in my right.

DC POWER 180amp is almost $750CAD so that's completely out of the question lol especially since it only has a 2 year warranty and the 270amp from them being $100 more and still only a 2 year warranty and I don't need 270amps lol, that's nuts!

BC DIESEL has the 230amp from XDP for $550CAD and warranty only 2 years as well, but warranty with them might be easier than dealing with a USA company.

XDP has the 230amp Leece Neville and price is comparable, but only a 12 month warranty so doubt I'll go with them.

The 135amp reman from NAPA I just put in is keeping voltage around 13.81 at idle and bounces between 13.75-14 at speeds and when I asked about the warranty I was assured it's a true lifetime warranty so I can return for a replacement at any time as long as I have the receipt so I like that and I can keep the 135amp Bosch behind the back seat as a back up.
This sound logical to you guys?

No. Adding more batteries will not do that. An alternator's ability to produce higher amps that are being demanded is what keeps voltage up - headroom. While the glow plugs are active, they will draw 200a, reducing to 100 amps after key-on. There is additional draw of 20 amps for engine control, and what the batteries require for recharge, which by 30 seconds after key-on will be 25 amps, dropping to ~15 amps at 90 seconds. All that is variable depending on the temperature and battery capacity.
So, demand is about ~145a while the glow plugs are on. While off, it all depends on the alternator output. With a 110a alternator, the demand may be 50a when the glow plugs are off or with a 140a alternator 50a, quickly going down. That doesn't last for long.
It's crazy to spend a lot of money just to have the voltage high during the 90 seconds of glow plug activity.

A few years ago I had done some research on a few brands of high output alternators. At that time I had decided that for me, it would be Mechman or Singer if I had to ever buy another one. There probably isn't any (new) concrete reason to change my opinion on that. I dd a quick search or two and it seems like things haven't changed a lot in the last few (3-5) years.
One thing is for sure - every brand seems to have its fan club AND its haters!
These two companies have "endured" over a lot of years and their reputation is as good as any other brand ...... and better than most from what I see.
