Replacement alternator
Posted: 21 Jun 2010 21:40
I've had battery charging problems ever since I purchased Chuck Norris...
His previous owner replaced both batteries the week before delivery, but I thought nothing of it at the time. Pretty soon I realised that the batteries never seemed to charge properly, except after a looooong (i.e. quite a few hours) high speed trip. Once I installed the Madman engine monitoring system I had a digital voltage readout in front of me that showed the alternator only reaching its regulated voltage at around 3000 rpm, which equates to way above the legal highway speed
Two attempts at rewiring & upgrading the alternator made no difference whatsoever. Neither did adding an additional cable between the alternator and the primary battery, replacing the drive belt, etc. etc.
When I turned the motor off after three hours or so of playing around at Mahem with the Nissan club earlier this month, Chuck refused to start again because the batteries were flat. That was the final straw and I started shopping around for a replacement alternator.
Nissan did their usual trick of telling me that there were no Patrol alternators available in stock in good old Mzansi, that a replacement would take a month to arrive and cost me two month's worth of salary. Nobody else in Pta had a 2nd-hand item for me either, so I started looking at the Lucas/Bosch/Delco route.
I knew that I would have to do some work to make it fit, so I decided to go for a BIG alternator while I was at it. A friendly & knowledgeable bloke who assisted someone else with alternator issues on the Nissan4x4 site came to my rescue. He went brochure scouring and found that Bosch had a decent unit, but no stock in the country either. Parts for that unit would have been the same story
We settled on a Delco Remy 21SI unit in the end. For those who don't know - the company claims to have built magneto chargers for the first horseless carriages, was part of GM from 1918 until 1994, and renamed themselves to Remy International in 2004.
