240 amp H1 alternator for classic range rover

[blue bomber]

I'm not sure what you're saying exactly, but even on an old Series Rover with a 35a generator all you'd need to upgrade is the alternator to battery (or fuse box) cable.

Light gauge low strand wires, non sealed connections, precious few grounds and a dynamo!!
Need I say more.

Yes, you are right . I suppose you could bypass all of the original crap. But it's foolish to keep the original harness. I kept the original dash board and switches. I just used superior wire,soldered ( no cheap and nasty Lucass crimps) all connections and used weather pack relays for anything that carried any type of load. Not mention lots of grounds!! Lucas, prince of darkness wasn't conjured up for a laugh, it's based on fact.

That may be, and someone might want to upgrade all that for various reasons, but using a high output alternator won't have any bearing on the vehicle wiring, aside from the alternator to battery cable.
If nothing is drawing 35a, it's not suddenly going to start just because the vehicle had a high amp alternator installed. That was what I was saying.

Well if you put a higher amp alt in a rig there are several conditions that can draw more than the 35 amps. A low battery will draw more than 35 amps, or jump starting another vehicle etc. lots of ways that a new larger alt could over tax the stock wireing.

To each there own.. I recommend upgrading the wireing when installing a high amp alt.

Just my .02

Even if you're operating a 450A electric winch, tell me where that 240amp is going to go, other than through the alt->battery cable (which I said should be upgraded), that would require you to upgrade your vehicle wiring.
You could install a ten billion amp alternator and that 5 watt tail light is still only going to draw 5 watts.

For the OP, if I'm reading the ETM correctly the stock alternator to fuse box wire is 15mm2 which is midway between #6 and #4. So using the smaller #6 as the figure, at full alternator output there would be a volt drop of 0.38v which is acceptable (I'm estimating a 4' cable length).
#4 would give a volt drop of 0.29v which might be worth going to if there are loads often requiring the full 240a output of the alternator.
Of course, these are new wire figures. If your existing alternator to fuse box cable is corroded, then the volt drop will be greater so it would be good changing it if it is. But you could go with an OE cable without issue. Not that I would because you can go larger aftermarket for less money than OE.

over the years i learned one thing about land rover owners they love to cryyyyyyyyyyyyyyyyyyyyyyy. and stick with the original part, even tho it can be junk.

my rover is 100% not original em i happy? hell yes i am happy . 240 amp alternator kicks a.ss and rover runs beautiful, .

we am not going to spend 300 bucks on some Lucas crap and wait 5 days in the middle of nowhere when i can get my good old American part and done deal.

enjoy your rovers .

Not me. I've always used other parts if I can find something that works. The decision is usually based on some balance of price, availability and level of modifications needed to use it.

that's what i think too. if it fits, and price is right then its made for land rover. we already know that land rover is not the best engineered truck ,so if we can put something else that works better then why not

That's pretty much all LR did when they made the trucks. Most of the parts not specific for the trucks came out of parts bins for other vehicles. Morris Marina door handles on your Range Rover and Discos anyone??

Love this thread. FWIW - Jeeps are the same way. A conglomeration of parts that results in a pretty capable whole, but with some prudent upgrades can be substantially better.

I just upgraded the primary wiring on my 2005 Jeep LJ while doing a battery re-fit/upgrade. One thing I now feel more strongly about than ever is that the OEM "fusible link" which is between the alternator and the PDC/battery should be replaced with an appropriately sized ANL fuse. If you substitute the word "fusible" with "burnablewhenoverloaded", you will see what I mean. Then look at where that consumable component (an undersized section of wire) is located. On a Jeep is it bundled in with and near other primary and secondary wiring. Collateral damage if you overload the charge wire is guaranteed.

I have personally driven a vehicle that suffered a catastrophic dead short in the primary wire from the alternator that resulted in the fusible link doing its job. Luckily the short was quickly found, and the fusible link was replaced, and collateral damage was minimal. The light show from the arcing (it was at night) was impressive! And I was driving the vehicle at the time! It was an old Dodge van, BTW.

Just some semi-relevant ramblings from a Jeep guy. Carry on.

So is the H1 it has parts from Ford GM and DODGE. not to mention seats are from German city bus and radiators are made by BEAR same company that's makes for BMW. Or MBZ

overall I think land rover did pretty good Job on parts but the problem is more aperant when u drive true some town that almost don't see land rovers. Now try to find parts there lol. Good luck we have to be creative then. One thing also noticed if u need parts and u call them most of the time they don't have it of it will many days before they get it. So it's the best to take the damaged part in and tell them plz match with another part. And your best friend is always. GOOGLE. LOL
