Hi people . My first post .
I have a 1989 turbo diesel Landcruiser with a 24 volt system . The alternator , for many years has needed to be spun up before it began to produce power and the dash lights extinguished . About 1250 engine rpm or three times that for the alternator . Recently it would not work at all so I pulled it off and gave it to the auto electrician . The regulator , brushes , bearings and the vacuum pump seal were replaced and I re-fitted the unit to the vehicle .
The alternator exhibited the same problem but now needs nearly 3000 engine rpm before it triggers and produces power .
Three wires to the alternator through the plug plus the main battery connection . The two 24v connections in the plug have power . The third is for the dash lights .
I pulled the unit off again and it bench tested fine . The auto elec. is a guy with a lot of experience and he is baffled . As am I .
Hoping someone can help
