Alternators and MAFs

[Hoges]

Last week needed to make a quick trip to Sydney and Canberra. 4 adults on board and due to need for a vehicle etc was easier to drive than fly...

MAF: took advantage of the excellent GBP/AUD exchange and got some bits in from the UK .Had a sneaky feeling that the MAF was below par due to some useful observations from others in this forum ;)
So, replaced the MAF and reset the adaptive values with the BBS Faultmate (10 min job all up) and we set of with a tank full of 95 octane down the Pacific Hwy. stopped at Taree for the night. Bowser fill/GPS distance: 11.7L/100km:D
What's more, rarely did the vehicle drop back a cog on long inclines...didn't accelerate much either, but held its momentum whereas before it would drop back even to 2nd at 95km/hr:mad::mad: :mad:
So far so good

Return journey last weekend got a few km from Karuah and tacho/speedo behaving erratically .. strange words on message centre: alternator problems. NRMA bloke was a graduate of the Neil Armstrong school of field repair and tapped it with a hammer:eek: Bingo, charging again. Limped into Tea Gardens and cooled heels for next 48 hrs waiting for "Rod" to open his wondrous shed @ Tea Gardens auto-electrical ...he's a Bosch service agent . He was able to re-solder the brushes and regulator and get us on the road (thanks Mate!!.)..NO regulators for that alternator available in Australia according to Bosch... other comments on the Net indicate it's supposedly non-repairable...but have found aftermarket source.

Moral of storey: add alternator to trailer load of spares to carry when going to the shops... probably cheaper than several nights extra unplanned accommodation and meals...

Did you go for a genuine Bosch Maf or one of the many aftermarket ones?
I fitted one of the cheap ones to my Merc a couple of years back and it transformed the performance and is still working well.
I clean the maf on my P38a every year but have been thinking it might be worth $50 to swap it for a new cheapie one

Do tell. I have my old alternator in the cupboard.

Hi Wayne, I believe it's an aftermarket one I got from Range Rover P38A--Fuel-Emissions (http://www.britishparts.co.uk/.sc/ms/cat/Range%20Rover%20P38A--Fuel-Emissions).

If it's a "replica" of the original then it's a good one: including all other stampings etc except for no "Bosch" trademark... could even be a Bosch but made for the after market..

Ron, try "Bosch Alternator Voltage Regulator BHA Landrover" on eBay ... $US34 approx. It's an aftermarket part because, apparently, the original fitment is supposedly "throw away" :eek: couldn't find a Bosch regulator listing for the 150 AMP alternator. The regulator does have a part number 1197311549 which matches the advertised one.
PM me if you want one...my brother lives in the USA and is going to send me one in the mail...

cheers

Thanks Allan.

I'll be in the US in less than 4 weeks so I could order one now for delivery to rrtoadhall whom I will be visiting.

I had my alternator die while on my way from Melbourne to Townsville. Luckily for me it happened in Canberra and PaulP38A quite generously loaned me his spare alternator until mine was repaired (i've still got it Paul - waiting for PM on address).

Hoges is correct in saying that you cannot get regulators or brushes for that alternator in Australia. Mine was rebuilt in Nowra by a relative and cost me $300 (thats parts only). If you can get a whole new 150 amp alternator for cheaper somewhere else i'd get it while you have the chance! The bits for mine came from Germany (took two months to get here too)...

Cheers
Keith

Hi guys,

oh dear, Frostie is in the dealer workshop waiting for a new alternator :eek:

Do I need to take a loan out against the house now?

If I were home I would sort it out myself but I am away at work and SWMBO is dealing with this, and she isnt happy about it either.

So, even if I suggest a rebuild the auto sparky isnt going to be able to get parts???

omg....
oh dear.

Mick.....

If anyone is after an alternator you would do well looking in the markets section

Hi guys new to the forum. My 2000 Disco II alternator just puked on me as well last week. The guys over here in the US forum are advising us not to purchase reman alternators from the local auto parts stores because the voltage regulators aren't original equipment and are not reliable.

Hoges is right the OE part # is 1197311549 however the part on eBay is not OE equipment and I would hate to see any of you spend $20 on a questionable part. However I was able to find it at RockAuto for $51 and Summit for $58. Only thing I don'g understand is my alternator say's its a 130 amps not 150? In the short run I did decide to be the lab rat and found what was listed as a "new 150A" alt from a manufacturer in CA. I will rebuild my failed one and keep it for a spare and will let you know if the "new 150A" survives a year without failing.

My personal experience with MAF is to do as the other member suggested I clean it with MAF cleaner once a year and stay away far away from K&N filers. K&N filters are fine in carbonation vehicles but I personally would never use them in a vehicle with a MAF because the filter's oil blows onto the sensor and causes the poor starts, jerky acceleration like you have a dirty fuel filter, poor performance, and gas mileage. Years ago before I learned of the MAF cleaner I decided to be cheap and buy a after market MAF on eBay for my 1995 BMW 540 and the car never ran the same and couldn't return it. Then I had to shell out the $350-400 to buy a new one. Looking back if I were in the position again I would have picked another one up in a salvage yard and saved the money and the hassle.

g'day 00 Disco II and welcome to the forum!

You're correct, the part I got from ebay ..Wenzell's garage somewhere in rural USA if I recall... :D is not OEM for the simple reason that Bosch do not supply them other than in a brand new alternator :mad:... in every other respect however, including 'manufacturing marks' the substitute is an exact replica of the original and works very well indeed! You are most fortunate to have access to a competitive market where techie stuff is available at reasonable prices! Enjoy your LR experience..it can become addictive:twisted:

There is a firm in the states selling COMPLETE new units they make themselves for a very good price, I think they sell on e-bay
The 150 amp from the P38 will fit the disco and provide an upgrade.
I have seen quite a few second hand Bosch 150a units on e-bay US, one new one went for US$50. I bought it!
