What would be the simplest way to wire that so the amp meter works? | | | | | Joined: Jun 2006 Posts: 693 'Bolter | | 'Bolter Joined: Jun 2006 Posts: 693 | the ammeter should be wired in series with all the power the truck uses except for the current going to the starter motor itself. for negative ground vehicles, the positive lead from the battery goes to the starter (or solenoid). do not disturb that wire. from there the current is routed to the rest of the vehicle. it is in this lead that the ammeter should be inserted, that is this wire should be interrupted by the ammeter as it is common to all current drawn except for the starter. so this wire should go from the starter/solenoid terminal to the + terminal of the ammeter, then from the - terminal of the ammeter to wherever the interrupted lead went before the ammeter was added. | | | | | Joined: Jun 2011 Posts: 5,096 Crusing in the Passing Lane | | Crusing in the Passing Lane Joined: Jun 2011 Posts: 5,096 | Easy to check which way to hook up to ammeter, if headlights are turned on with the engine idling or off, and the meter shows discharge(-) then it is hooked up properly, if (+) then switch the wires on the meter.
