[QUOTE="Magnetoman, post: 47338, member: 2806"] The potential problem of both of the above techniques comes from the fact they require the mounting bolt to be removed from the unit in order to measure the resistance. Otherwise you are trying to see the difference between 0 Ohms and 0.5 Ohms (which isn't even possible with the bulb and quite frustrating, if not borderline impossible, with anything but a good ohmmeter). The advantage of using an LCR meter or buzz box is both work with the unit locked on the taper. No matter what, you fiddle with the timing as much as you want with it loose on the taper and then tighten it down. With an ohmmeter or buzz box all you can do when you tighten the mounting bolt is pray that nothing changes as a result. Since you can't measure it after the fact, you then have to pray again that your first prayer was answered. However, with an LCR meter you are easily able to confirm that the timing hasn't changed as a result of tightening the mounting bolt (or, see that it has and thus are able to deal with it). [/QUOTE]
