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....
