I just got my 914 back on the road today after a complete makeover. Among the items we upgraded was the alternator. Now that the car is running it developed a screeching sound after 120 test miles. I’m attaching a video clip where we were able to reproduce the noise by pulling on the fan belt. The alternator and tin are tight and not wiggling.
Any thoughts? trim.08AC758E_52EC_4014_A7A6_B0077D8B6420.MOV ( 2.75mb ) Number of downloads: 97 |
