Re: Leece -Neville Alternator external regulator install

Thanks for the information Oliver.
Do you have the Leece Neville 175A alternator on your boat? If so the one picture that would be helpful is the actual wiring of the regulator behind the cap and the new connections into it. And also if you have the LN175, it would be helpful to know the max current that you draw from it?

I used the VSR sailors project regulator from Al Thomason.
I am very satisfied with it.
Since then I dont have wear off pullys and the regulator offers all parameters to customize beside all standard charge programs.
I dont know if my wiring or fotos will help you?

Does anyone know what the safe continuous output for the LN175 would be? Or any information on the out put curve specific to this alternator. I don't recall seeing it. Just the 175 amp rating.
Traditional alternators can be a problem.
Remember though that on our boats there is a 1:2 ratio between engine rpm and alternator rpm so when the engine is doing 1000rpm the alternator is doing 2000.
This is where alternators like Delstar and Idlepro Extreme come into their own. These are 220/250amp alternators that can deliver 80-90% of rated output @ 2000 alternator rpm.
The standard LN175 can't do that and if you increase the rpm to produce more amps it will only do it for a while before everything turns to custard.
We have big battery banks that can have very high charge acceptance rates with AGM, firefly or lithium batteries, so you need to think about these things very carefully in designing and operating a system that will achieve what you want safely.
