Everyone needs one of these specific units , or another brand with same features. https://www.jaycar.com.au/automotive-dmm-with-inductive-pickup/p/QM1444 The price was nearly $80 a couple of years back. This is a great price. The advantage , even for the electrically and mechanically illiterate, is it has dwell as well as usual V and resistance functions. A bonus is thermistor ( temp) and RPM function s. If starter is slow at least you can check if the battery voltage is the issue. If engine won't fire but you have spark, or its firing badly at low revs, then a common issue is closed points. The dwell test is much easier than trying to check points gap with a feeler guage. Just set meter and fit 2 clips and get your reading. An essential diagnostic tool if you are stuck and seeking advice on the phone or forum. We can run thru a few basic checks that fix a lot of common faults. Without the info for us to diagnose you are going to be calling RACQ or similar. Cheers.
