    Tachometer from 1984 Nissan 720

    Google Dotson 720 factory service manual if you have not done so already the files is too large to upload it includes schematic for RPM gauge tachometer & it’s free to download. and believe me I know the price is high for an OEM product. Also, I think they replaced it. The H bridge with a 23...

    LGS4056 Not Working

    I understand completely. :cool: You must level shift your output from the MCU 3.3volts to 5Vdc this is what is required.(research transistor voltage level shifting)Your 2.2k Ohm current program resistor should be reduced to 2k Ohm for a 500mAmp Charging current. when combining simple circuits...

    LGS4056 Not Working

    You must show the entire schematic your MCU does it operate on 5 V or 3.3 V is this is modular system.?You must show your connections or inter connections to the various modules.whoever gave you thumbs up on your schematic should keep there thumbs where they belong and try not to break any...

    What can I use instead of a 27R resistor?

    Welcome to Maker Pro. If you use two 47 Ohm put, them in parallel will give you 23.5 Ohms. With that said this is a diagnostic harness ;I would wait & purchase a 27 Ohm 1% resistor.

    LGS4056 Not Working

    Welcome to Maker Pro. From the data sheet LGS4056H has four charging processes: short-circuit (SC), trickle (TC), constant-current (CC) and constant-voltage (CV): short-circuit charging (SC) can charge OV batteries; You cannot charge a lithium ion or Lipo battery when it is 0 Volts...
