Problem With Justjap Autogauge Oil Pressure Gauge

Hey all, i just installed a set of the justjap autogauge gauges, oil pressure, temperature and water temperature all with the warning light/beep.

Wired everything up, started her up and yay, they all worked.

But then one minute later the oil pressure gauge dropped to 0 and started beeping at me. When i give it some revs the pressure goes up and seems to half work. but once i get off the gas and let it idle, it just drops straight back to zero.

I've unplugged it since i cant stand the beep.

Just wondering if anyone else has encountered this problem with any type of electronic pressure gauge and found a way to correct it?

PS: im considering the fact that it may be a faulty sender unit, but I cant get in contact with justjap until monday.

Im thinking that you might have an oil leak? same thing happened to me, the sandwich plate was leaking and oil pressure was very low, managed to dump half my oil in a 10min drive too...

ive got similar gauges but without the warning function which work perfectly... lowest its gone is 10psi after a thrash :thumbsup:

did you put + on - and vice versa? or are you sure they are on + and +

wow nice work blaming the quality of the gauges first up.

we ran the Just Jap Auto gauges on the car at Targa Tas and they worked faultlessly. I think you should start with checking the install....is it getting 12v+ and good earth? is the sender earthed properly? what v does the signal wire send when the motor is running? does you standard gauge show the same thing? does your factory oil pressure warning light come on? how much oil does the dipstick show? how did you connect the sender to the oil?

all the senders are earthed directly to the shell

ill attack the rest of the wiring with a multimeter and see what i can find.

my standard gauge does the same thing but only on and off, sometimes it works, sometimes it doesnt. the warning light has never come on.

the sender is attatched to a sandwich plate along with the temp sender

checked the oil yesterday and its fine, ill check it again in the morning to make sure it hasnt moved.

couldnt see any oil leaks yesterday, ill check in the morning aswell

i think the gauges are fine, must have done something wrong somewhere

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
