  1. Mike I have a question on the Cobra Alarm.

    Last time you taught me how to bypass & to start my Cobra alarm by putting pins at the end of the cobra alarm plug. I was able to start it, my question is -- by leaving the jumper is there a battery drain when the car is off?

    My other question, I had  time to check the Alarm fuses under the dash (yellow plugs) and the fuses are not blown. Why my  car won't start? Do you think I need the reset procedure using my emergency touch key?  Do you think my cobra alarm is dead?

    Thank you CHE

      Sorry for being so bad in answering.  There should be no drain because of the bypass.  I think that your immobiliser is dead

  2. Update on my oil pressure light on idle. After all the nasty job removing my oil pressure switch, the time I spent under the engine, the hunt for original oil pressure switch & the cost of the new replacement oil switch, I DID NOT FIX THE darn PROBLEM. I capped (plugged) the original oil pressure hole (stupid hole). I installed a TEE adapter on the spare hole in front of the oil filter housing, I installed an analog oil pressure gauge then the new replacement oil pressure switch (see picture). I started the car, the oil pressure reads 50lbs (engine cold) I drove 3 miles
  3. The socket on the right that used to remove the oil pressure switch was made by craftsman. The wall is much thinner than some brand socket. I was able to removed it without doing extra procedure. It was very tight, i can barely twist the socket but it will work. The socket on the left is also 26mm but 20% thinner than the craftsman. I brought to the machine shop to turn. For sure, this socket + the oil switch will have no problem fitting on the same fooking location (sorry for my latin, i was so pissed). But the problem, I can't find the stock oil switch. I called every Lotus vend
  5. Update: I was able to remove it by using a thin wall 26mm socket. Better yet, I bought a cheap 12 points 26mm and brought it to a machine shop to turn and to make it more thinner wall (just for this job). Now, the hardest part is finding the stock oil pressure sensor. Any after market oil sensor will give me a hard time to install it. Can you recommend a part store in UK and I will try my luck.
  6. oK i WILL Try it again.... Thank you
  7. Another Lotus engineering sweet spot. I was trying to replace my V8 oil switch but no luck. I have a lift, I removed the oil filter to access the oil switch using 26mm socket. Somehow socket is the only way to snake out the switch. Unfortunately, even the socket side is too thick and will not sit flat because the oil filter housing on the way. I was not able to do the job. I was thinking of grinding my 26mm socket so to make the wall thinner. I was also thinking removing the 4 bolts of the oil filter housing but the 4 bolts are so nasty to remove too. No room for the 2nd &
  8. I did not find the stock lotus Esprit oil switch. I found a 20 pound switch (20 low & 67 high) that i think will work, but the thread is not m10 x 1.0. I bought a small female to male adaptor with m10 x 1.0 thread. I also bought an analog oil gauge + the oil switch but the darn vendor was late on sending the item. I left for DUBAI & MANILA. I will be back on the 30th and plan on installing both parts. So, no I was not able to install & test. I think I will buy the bosch you mentioned too. The one I bought and the bosch both dirt cheap, might as well have two to test. I will
  9. "The minimum oil pressure at idle is specified as 1.4 bar so the switch needs to operate a little below that pressure." I think this might work 1.2 bar at low oil pressure. The thread also the same M10 x1.00
  10. Thank you Mark I will contact VDO
  11. I called one of the lotus part dealer and told me that the stock lotus oil pressure switch is obsolete and discontinued. The replacement is the VDO switch. Anyone here knows which VDO oil pressure switch in the 4 links below ? 1. 2. 3.
  12. Oh by the way, do you happen to have a picture of the lotus oil pressure switch? I LIKE TO SEE the part # that was stamped in the unit, also the brand name. I have a friend that works in the auto parts and he said he will try to cross reference. Thank u
  13. Ok Thanks Mike, At least I know how the PRV works now. Yes I will surely do two things. Change the oil pressure switch and put a gauge. It's just to hot here in South Florida to even work inside my garage. I can't wait a cooler days or winter to come [2 mos to go}.
  14. Thank You EspritV8black, I had a chance to change the oil and filter yesterday. I used 15/50 mobil 1 and M1-204 mobil 1oil filter and the result was the same. The oil light was flickering and on during idle only. The next move is to change the oil sensor switch and hoping it will solve my problem. I saw where I can connect an oil gauge. The hole is 10mm with 1.00 pitch. I also saw the oil sensor switch (could be a bitch to replace it). On the top of the oil switch, I also saw the oil pressure relief valve. May I ask what the oil pressure relief valve does or function
  15. Well, never had this problem before when I live in snowy cold New England USA. This year I moved to the Blistering heat sunshine state Florida. I have this low engine oil light during idle only. The idle rpm is ok (a little over 1000 rpm) I still have the original oil when I shipped the car to Florida. I don't remember the oil weight that was currently in the engine. My guess its 10/30 mobil 1. I ran out of idea except I plan to replace the oil using 15/50 Mobil and hoping to cure this issue. My guess was, the oil is too thin or too hot and the sensor turning the oil light on. My eng
