I'm chasing Vacuum lines and checking, fixing and replacing them, as I do I'm running across things that don't look quite right some of which I'm unable to Identify, Any help you can give is appreciated...
Can you tell me what this is, Does, it was bolted to the bottom of the Battery box. does it need to be grounded. Attached image(s) |

Thats the resistor pack for the fuel injectors..
no need to ground it but it would be better screwed down. Second pic is the dual relay for the FI... same advice |

Those are both parts for the FI, The one on the battery box should be bolted there, and the other one just bolt it anywhere taht is close to where you found it. I dont think the one needs to be grounded but I am not sure. I would bolt them both down in anycase.

(IMG:style_emoticons/default/biggrin.gif) can't help you much there, don't know anything about L-Jet. my 1.8 was already converted to D-Jet when i got it. much less parts to worry about.

Both should be screwed to the battery tray support.

Andy,
I took this from the Megasquirt site...gives a little info on why the resistors: QUOTE Pulse Width Modulation Injectors are either high impedance or low impedance. High impedance injectors (usually about 12-16 ohms) can take a 12 supply directly, without a form of current control. Low impedance injectors (generally below 3 ohms) require some form of current limiting. With MegaSquirt, you can use resistors to limit current, or you can use Pulse Width Modulation (PWM), which is a software solution built in to MegaSquirt. Levi, It's a good idea to become familiar with these parts, helps troubleshooting down the road. The dual relay item: with key on, flapper opened (manually or by the vacum of the engine), this d/r gets energized, when it does, it powers the injectors (injectors fire when grounded by the ECU) it also turns on the fuel pump...this is good to know, if having problems or testing the fuel system, you can simply turn on the ignition, and open the flapper box, now you should have fuel pressure..(as long as dual relay is working properly) |
