Alternators
Before carrying ou t tests on the alternator visual and safety checks are in order.
Check if the parking break is applied and if the car is in neutral. Are the warning lights operating and all ignition accessories turned off? Check the connections if there is any fraying of wires, loose connections. Look to see if the alternator is mounted to the car firmly and the condition of the fuse's and fusable links. An alternator has a drive belt. Check the tension of this if loose or frayed and cracked, replace it.
Belt: The belt was in good condition and doesn't need to be replaced. the tension is good.
A no load test was carried out.
Recorded OCV- 12.6v
Regulator voltage spec- 13.5-14.5v
Regulator voltage reading- 14.0v (pass)
No load specs for carburettor 5-12amps Fuel injected 10-18amps
No load output was 9.5amps (Pass)
The charging voltage under load spec equals OCV+0.5= 13.1 .
The charging voltage under load was 12.43v
a voltage drop test was carried out. The spec between the battery positive post and B+ (alternator output) whilst engine is running needs to be less than 0.20 volts.
Test- 0.01 = Pass
Spec between battery negative post and alternator body whilst the engine is running is 0.20volts
Test- 0.05= pass
All the voltage drops added together is 0.06 and the maximum allowed is 0.40volts . pass
Overall the charging ststem on this car is good and no alterations are needed.

good reflection-- tests and results explained, final conclusion is what we are looking for
ReplyDeleteSo what else should i include? The test shows that no alterations are needed?
ReplyDeletewhat you have put in is fine. my comment was to reinforce the need for the final conclusion to reflect on the results of your testing and what they mean
