So I have a 930 Tach, and every time you rolled it around it would rattle. I figured that someone dropped a bulb in it, but before I did something with itI needed to find out why it rattled so.
So let the autopsy begin. (IMG:style_emoticons/default/screwy.gif) 930 Tach - so what makes these so damn expensive (IMG:style_emoticons/default/confused24.gif) That little 1 bar boost gauge hosed in the face. (IMG:style_emoticons/default/confused24.gif) Tools of the trade - custom made for this job. Opens gauge bezels like a can opener. Just work your way around, at least 3/4 of the way. All opened up (IMG:style_emoticons/default/piratenanner.gif) Flip it over remove three screws and one nut. And removed from the can More Detail just for you Tim (IMG:style_emoticons/default/beer.gif) Interior of the can And now what was rattling around inside the tach. (IMG:style_emoticons/default/poke.gif) I was right (IMG:style_emoticons/default/piratenanner.gif) (IMG:style_emoticons/default/happy11.gif) Can't wait to see what happens to this now (IMG:style_emoticons/default/shades.gif) |

It's amazing how VDO stuck with their same board design of over 20 years. Instead of spending a few bucks by doing a simple revision of the circuit board so it profiles around the boost gauge, they just used what they had and crammed it all together. (IMG:style_emoticons/default/headbang.gif)
Notice how they had to tilt the main board so it fits around the boost motor. |
