The second capacitor was added due to the fridge relay circuit. It is there to absorb the coil voltage spike on turn off. Let's not confuse quality with design issues. One describes consistency and fit finish. That small bearing in the insulator housing is a poor design just like the drive belt not wrapping around the crankshaft pulley.

They are mechanically unreliable. I am pointing to the bearing on a small end. In my Westy I spotted the shaft wobbling after 14,000 miles. The nylon sleeve the bearing had as a seat was very loose on the bearing and in the bore. The bore became out-of-round and had conicity. I decided not to bother with opening the bore and making larger sleeve and got another alternator remanufactured by Bosch. Out of curiocity I took it apart and witness the bearing and the sleeve to be loose. That alternator had even shorter life. The seat was enlarged and TOLERANCE RING installed. The problem was cured. Speaking alternator. The original Bosch 33 x alternator has 2 capacitors. Most alternators I've seen on Jettas do have one capacitor. Example Bosch 27 X ( I do have one new ). Can somebody explain to me what the second capacitor is for. Can I use Bosch 27 X alternator when I want in My 1987 Westy? Thanks in advance. |
