Where does the rpm (rev counter) get its feed from
I am installing an lpg kit to my jaguar, and one of the requirements is to take a signal for the rpm.
On that basis, the car has individual coils so taking a signal from one of these only gives you half the true rpm speed, ie dash shows 700, the individual coil shows 350. as the coils are constant +ve feed and switching -ve earth (as far as I can tell).. On that basis, if I 'piggyback' the -ve for 2 coils,(which may give me the full rpm signal) I suspect this will not work as the signal from one coil pack will travel down the wire to the other coil pack and cause an issue with the car's ecu.
I would greatly appreciate any opinion on this issue.
great car though.

There could be several reasons why the rev counter of your 1992 Opel Monza is not working. One possible reason is a faulty instrument cluster. The instrument cluster is responsible for displaying various information, including the speed and RPM of the vehicle. If the instrument cluster is faulty, it may not be able to display the RPM accurately or at all. Another possible reason is a faulty RPM sensor. The RPM sensor is responsible for sending signals to the instrument cluster, which then displays the RPM on the rev counter. If the RPM sensor is faulty, it may not be able to send signals to the instrument cluster, resulting in a non-functional rev counter.
To fix the issue, you can start by checking the instrument cluster and RPM sensor for any signs of damage or wear and tear. If there are no visible signs of damage, you can try resetting the instrument cluster by disconnecting the battery for a few minutes and then reconnecting it. This may help reset any electronic glitches that may be causing the issue.
If resetting the instrument cluster does not work, you may need to replace either the instrument cluster or RPM sensor. It is recommended to take your vehicle to a certified mechanic or dealership to diagnose and fix the issue properly.
In summary, a non-functional rev counter in a 1992 Opel Monza could be caused by a faulty instrument cluster or RPM sensor. Resetting the instrument cluster or replacing either component may help fix the issue.

The speedometer gets its signal from the Vehicle Speed Sensor (VSS). It is usually on the transmission. The RPM gauge is a separate signal, from the engine controls.
hi your issue is that your car which starts with petrol then switchies over to lpg for which youll already know ,but the problem lies within the cylindar heads as it can only be 1 of 3 things =1, your valve seals are worn excessively due to the lpg as that runs at a higher heat density which stretches the valves which in turn causes then to wear and that reduces the power ie lack off,as it puts the ecu into limp mode (safe to protect your engine) as its a common fault on ALL lpg conversions.as that is also the knock on effect with your master servo (brakes).as i fix approx 3/4 a month. hope this help's to clarify what is wrong ok
I doubt if there are LPG kits available for Diesel engine? LPG is for petrol engines only. However there are other kits available which will partially use LPG and diesel to run engine, these are not popular.
All LPG kits are custom to vehicles they are being installed on. The possible problems are the same with all models. They include Leaks, lose of Mileage and the obvious dangers of filling the tanks when needed. I will tell you this much, it is unlikely you will save any money converting to LPG as most conversions get far less mileage than they do on regular fuel. Also, a Conversion kit is a full conversion. Once installed you are not going to have the option of switching between the two when the LPG system fails. You would think with the faster burn rate you would have better acceleration in LPG vehicle and better Mileage since the Typical LPG fuel is a higher burning and cleaner burning fuel but in reality it it usually just the opposite in conversions and they have a tendency to vapor lock more often.
The rev counter could be faulty.
I hope the engine is responding ok on accelaration inspite of the rev counter being stuck on 3000rpm , if so thn its definately the rev counter being faulty.
lots of old cars were + earth but not all .dont think this will make any difference ,is this rev counter for a 6 pot or four?? check terminals on back of unit??does one look as though it the earth ?? if not then one goes to earth and the other goes to the points side of the coil.easy
