The fsm instructions have an installation procedure that says something about being careful not to damage the o-ring. I suspect you'll fix it with new o-rings and careful installation. You could replace all the rubber bits on the injectors, but...

Yep, more than likely the o-ring. I'd be just replacing all of them - they are cheap. If you pinched one you may have pinched two. Step h) above is important. Also, careful screwing down of the bolts that hold the fuel rail in place and clamp...

and a few more...

Older son was at a toyota event for the trade - for companies building after market stuff. Pics are 'cleared' for sharing. He sent some to me, so posting them up for you guys that are hot to trot to buy one. cheers, george.

Not quite right :) A zener has a break down voltage. It will break down (reverse biased) and conduct when you reach that voltage (it's not instant on/off...). Typically there would be a resistor in series to limit current and the voltage across...

I will! Electronics are one step away from black magic... eye of newt and salamander tail so far as I am concerned. :doh: But it never hurts to try and understand it better. :) Mark...

It's not actually quite like that... The capacitor is used as part of the timing, the transistor (and leaking zener) are what control power to the ring. Read my write up in the link further up and it explains a little about the circuit and the...

He is an electrical engineer. That may have something to do with it. Or, maybe he feels lucky. :)

lifepo4 is a 'safe' chemistry versus li-ion. It will not 'catch fire'. The battery also has a BMS to protect from charging when the battery is too cold or too hot. The battery is operationally safe to 55C. I've never seen 60C in the front/battery...

Thanks for your concern, but the lifepo4 will be just fine in the battery case in the front area of the engine bay and so will the charger PETG is fine for this application. Cheers, George.

Well, a bunch of weekends and planning. Re-doing my dual battery setup to use a lifepo4 as the aux and that has entailed a bunch of planning and rethinking my existing solenoid based system (that has/had been working for the past 20+ years). The...

^ you have to look closely at say an 80 series (others are similar) and you will find there are NO ground straps to the chassis. It is not part of the ground circuit in any way. The 80 (as the example) has a big ground connection from battery to...

My home made cover, scrap marine vinyl, sewing machine, bit of time. > 20yrs old and 80 lives outdoors. cheers, george.

I've run hand made covers (I'm cheap...) on both my 80 (m12000) and my oz patrol (8274) for a couple of decades. Used some scrap marine grade vinyl material. The 80 lives outside (norcal) and patrol in a garage. The winches look pretty well new...

You can go to Lexus Parts Now and plug in your vehicle model then search Tube Brake and find the tube you're looking for. Most but not all parts for the 97 FZJ80 are the same as the LX450 with a few exceptions (HVAC, some interior and body parts...

I'm sure there's a limit, don't know offhand what it is. Something to verify in the product's documention/spec. Fancier units that gave scpi may have pretty fancy capabilities... cheers, george.

1 second was just an example. The fastest is 0.1 sec per change :) cheers, george.

You can program steps in the various modes. Below shows Constant Resistance and changing the resistance values every second. It will log current, voltage, power etc so you can get curves. You can save the data and then pull it into excel for...

I have and use a Manyuo electronic load. It's well proven and there's a few similar units out there. Fairly old school in terms on 'UI', but it works just fine. I've used for a bunch of years. Mostly as an electronic load for LED driver testing...

^ Agreed, misinformation in a thread that people will refer to is not a good thing. Landlocked93 clearly doesn't understand the distinction between a poor ground path and an ENGINEERED one by Toyota etc. He doesent understand how the body mounts...

If self jump-starting is on the menu then the current usage isn't any different. You talk about not having ground loops and then you suggest using both the body and the frame as parallel ground paths. That's a ground loop in my experience. It...

Sorry, but no. The frame is not a ground path. It may connect to the ground system via bearings, springs etc, but it is NOT intended to carry current. Again, there is no point where Toyota uses the frame to carry current. Current is carried from...

Yes, and tailshaft and bearings to axle etc. The point is that ground is via engine and body. Frame/chassis may have indirect grounding, but is not used as a ground path. I've got a pretty good grasp of ground loops - my EE work ensures I...
