Russ, Electronics are unpredictable. What would cause my tach to work one day, and the next read about half what it should? So, to remove, pop the four warning lights in each corner of the dash panel (BTW, you MAY need to remove the steering wheel, use a good quality 3mm Allen wrench if you find you do. Be careful, the screws are Loctited in and very hard to remove, use a quality, hardened 3mm Allen wrench!). Use a Phillips #2 screw driver and remove the screw located behind each warning light. Now the panel can be lifted forward. Just enough to reach behind. You will find one or maybe two electrical connections to disconnect. Then there are two thumb screws you need to remove, then the tach will come out through the front of the panel. I would recommend covering the steering column with a couple towels to protect the tach and instruments from scratches. Pack it carefully and insure it for at least $300 and send to a speedometer shop for repair. I sent mine overnight on a Monday to Palo Alto Speedometer and had it back (via Fed Ex)on Thursday. Just give Helmut a heads up that it is coming. I just checked, and he charged $150. | ||

Dave, Having considered removal of the tach, looking under the dash and rethinking it, how did you go about removing the tach?? Still hard to believe something would degreade while in storage...... Tom, actually we've had one solid monsoon season in upstate NY this year. I have been driving the TR on the few weekends not raining. Russ | ||

Russ, I just went through this, and cleaned connections to no end, to include treating with Stabilant 22a contact enhancer. The solution is to have the tach rebuilt or replaced. I found out that this is a VERY common problem, there is a component on the tach circuit board that fails. Any of the larger speedo shops that works on Veglia instruments will be very familiar with the problem. A new tach is around $300 from Ferrari UK. Repair from Palo Alto Speedometer is around $150. | ||

tap the tach with your finger  make sure you have cleaned the correct connections. BTW you should be scolded for waiting until July to bring your car out of winter hiding | ||

After an extended winter storage period, I have found the Tach in my 328 now only shows about 50% of the actual rpms the engine is turning. I have checked and cleaned the connections on what sensors I could locate on the engine and still have the problem. I should add, everything functioned perfectly before the winter's rest. If this were British I would look for a bad ground. Any hints or experiences would be helpful. Car runs fine, but I would like to get the tach back to normal operation. |
