Thought I saw it on an old thread but no luck now- what is the correct tention for the belt? will a worn tentioner cause this? I have a bit of a cold idle �chirp� I changed the belt last week and the routing is correct.. still the same problem. I hate to buy a new alt if I can replace a 1.00 part thanks P   Nick Harvey (Aussie_nick) New Member Username: Aussie_nick Post Number: 1 Registered: 02-2004 Posted on Thursday, February 26, 2004 - 07:05 pm:    I had the same problem with my tacho�..intermittent operation then none at all, replaced the connector on the back of the alternator and it worked fine till the wire snapped�.I think that the under bonnet heat causes fatigue in the wire, I replaced a section of the wire and presto�problem gone. Hope this helps Cheers from Australia   Josh (Badassm0f0) On Probation Username: Badassm0f0 Post Number: 55 Registered: 12-2003 Posted on Thursday, February 26, 2004 - 08:50 pm:    yeah i just used a leatherman and crimped mine to make a tighter connection and my alternator woes stopped, ie bad tach stopped.   Peter J Blatt (Peteb) Senior Member Username: Peteb Post Number: 339 Registered: 10-2002 Posted on Thursday, February 26, 2004 - 09:14 pm:    That connector for the tach, is bolted on the back of the alternator with a 8mm, mabey just take it off and give it a good cleaning and reinstall the little connector to the back of the alternator.   peter ziesmann (Peterz) New Member Username: Peterz Post Number: 19 Registered: 03-2003 Posted on Thursday, February 26, 2004 - 09:21 pm:    thanks all. Nick, how much of the wire did you replace? Guess I'll try and splice in as much as I can....
