1998 hilux altinator

[markcain2004]

hi i am looking at installing a duel battery system to my hilux

does anyone know what size altinator a 1998 2.7 petrol lux has?

[plowy]

Why the need to change alt for a dual batt system ?

[markcain2004]

isnt the altinator the thing that determines how much carge goes through to the battery?

if you have a small altinator doesnt it take longer to charge your second battery?

It will take longer to top both up if they are BOTH flat yes, but most dual battery systems you are working one or the other, rarely both. Depending on your application the best setup I have heard is just running another system, 2nd alternator, 2nd battery. Don't have electronics getting in the way then. Just need something to work the deep cycle when you are just cruising around.

an ALTERNATive



Damn I think I am funny

I know that a 95 diesel lux has a 70 amp alternator. The time it takes for your battery to charge is determined by your battery size, how empty it is, how thick the cable is running to it and how much output the alternator has. If your just running a fridge and some lights the alternator you have should be fine.

Being a petrol, i am not sure because the manual i have is only for diesels, i do know that the 2wd diesel has only a 55 amp alternator. It all depends on what your running off the auxilary. The more you drain and the more you use it the more youll need to charge it and for longer.

I think it's only 55amp. I've just upgraded mine to an 85amp bosch BXU1285 which is the perfect style of alternator for a 4wd. Vibration resistant, high tollerance bearings and puts out 85amps at something like 1600RPM. You can get a 110amp one but it doesn't output that until something like 6000RPM.

By the way, it's not directly bolt in but it does work with std mounts and an hour of stuffing around grinding and redrilling things.
