Find out simply if the surfaces of the battery posts have oxidized causing a high resistance connection. Use the ohms meter and touch the probes together. The meter will show a very low resistance. Now touch one probe to a battery post and the other to the battery cable clamped around the same post. You should get a low resistance reading again meaning that electricity can flow easily from the battery into the cable. If a high resistance is indicated, remove the cable and scrape it's inside and the post til both surfaces are bright and then reassemble and test again.
Check any type of battery cell for condition. Rechargeables should be 1.2v, Alkaline should be 1.5v and Lithium should be 3.6v minimum.
Find shorts and broken wires easily. Hundreds of simple tests can be done to make your life easier and free you from dependence on high priced service.
