Re: Alternator voltage spike

....... The starter motor and alternator are lightweight racing items from Brise and the battery is a Lithium Ion race battery. ........... Hi, well,then further: - from which car you use PCM (brand, year, part number from the catalog) ? - although you do not use injectors does the PCM have injecto...

Re: Alternator voltage spike

Hi, It seems your description of the problem is not very informative ... I dare to assume that because of incompatibility of your components or errors in their connection. Perhaps you see pulses of the injectors (which can have such a voltage), but there may be ignition pulses. It would be nice to s...

Re: voltage and current out of phase reality check

Hi all Awhile since i posted on the forum but i find i need a reality check this is of a screen print of a merc petrol engine injector voltage and current for injector 2 trace A is injector 3 voltage trace B is injector 2 voltage trace D is current for injector 2 voltage measurements took at ecu pl...

Re: Piezo injector operation. Current vs voltage

You can see the circuit ecu-injector as an oscilator circuit, electrons go from ecu to inj and reverse, but voltage to ground does not change polarity. Hard to explain. So in the first post, the diagram absolutely NOT TRUE. And on the examples from Steve and victor2k everything is correct. It was i...

Re: Piezo injector operation. Current vs voltage

Hello,

But why in the first example current starts changed  before than changing voltage
These two events must begin at the same time or how ?
Explain please.
Thank you
