Unlocking Automotive Electrical Secrets Can Meter Shunts and Parasitic Draws

I will show you how to test an alternator the right way for voltage and amperage without using expensive amp meters. You can read the amps on the sg200 screen. No need for the 2nd amp meter. Assuming it's installed correctly. What did the Soc say when the ... Monitoring system needs to know when engine is running. 3. The negative side of the battery cable can act as a current shunt. So, voltage ... To test for a parasitic draw, you should disconnect the negative battery terminal and place an amp meter between the disconnected negative ... Shunts are fine and yes they make up to 500 amp shunts and meters, but this seems overly complicated and unneccesary just to check for parasitic ... Yes it is really a sensitive voltmeter that is using the resisstance of the fuse as a shunt resisstor to create a tiny voltage drop. All lot ... - Grab a 1 metre length of wire that you can pass the necessary current through. - Wrap 10 turns through your clamp meter. ... - Zero your clamp ... verses the intermittent ones that just show up for a second and dissapear before you can catch a glimpse of the meter. I am interested as to ... In response to Donalex's questions: 1. The power to the float switch and pump remains on with the LED on and off. 2. the negative shunt is on ... A clamp-style multimeter can be used to calculate parasitic loads and help track down where the amps are going. Max Parker. Back from the Dead.
