    12VDC Power Conditioning

    Confusion!! The product specification at the link you provided states input power: 10-18 VDC. Your charging system is designed to operate within these parameters. You state that you keep blowing fuses - are you blowing the 5 amp fuses, or have you blown a 10 amp fuse? So....if blowing fuses is...

    TCI (or CDI) IGNITION TRIGGERING PULSE TOLERANCE

    Although the VR sensor generates a voltage, it is not used to power anything inside the control module. It is used as a signal which is interpreted and decisions are made based on it. The module has power and ground so it can work. THe analog (sine wave) signal goes into the control module and...

    Parasitic Draw/Drain specification.

    In the repair industry the rule of thumb is that the parasitic draw should be no more than 1/4 of the reserve capacity of the stock battery in mA (i.e. stock battery is 120 min reserve capacity, maximum draw is 30 mA). I have seen individual instances of published data per manufacturer, but it...

    Whats the Pefered Method to Wire for Voltage Dist?

    First - to answer your question directly - the most elegant is going to be to start with a single connection at the ECU and install a splice pack with a lead going to each sensor from that. Put the splice in a central location to the sensors it feeds. This splice can then be properly sealed to...

    Required Ammonia Pressure Relief Valve Capacity

    I have located additional information, but would like some experienced opinions to weigh in on this topic in general. From ANSI/IIAR-2008 11.2.7 "...In the case of a plate and frame heat exchanger, replace the DxL portion of the equation with a term equal to half the overall external surface...

    Required Ammonia Pressure Relief Valve Capacity

    Hello - please be patient as this is my first post. I am having trouble finding the basis for the required discharge capacity of a relief valve as stated in ASHRAE 15 (C=fDL). Are the D & L portions to reflect the vessel volume or the vessel surface area? I would initially think volume since...
