Electrical problems can be very difficult to diagnose. Bad starter, dim lights? Let us know of electrical problems you've encountered in your and how you solved.
Also suggestions for electrical upgrades like electronic regulators, fuel pumps, alternators, ignitions etc The voltmeter should indicate a voltage well above 14V. If I remember right it went up to 20V. If it doesn't get to this Renault 21 Savanna K48 1986-1994 Bosch S3 Battery 56Ah Electrical Replace Part then Alfa Romeo 75 162B 1985-1992 Banner Starting Bull 55Ah Battery Replace the field coil is death.
Measure the resistance between the DF stud Renault 21 Savanna K48 1986-1994 Bosch S3 Battery 56Ah Electrical Replace Part contact and chassis.
Replace the coil if you measure a too high resistance. It's also possible the field became demagitized or reversed. To get the field right again leave the link in place Renault 21 Savanna K48 1986-1994 Bosch S3 Battery 56Ah Electrical Replace Part make momentarily a contact between the link and the plus from the battery. If it Renault 21 Savanna K48 1986-1994 Bosch S3 Battery 56Ah Electrical Replace Part CCW you need to swap the field wires. Field coils are easily replaced once you get their mounting screws loose with an impact screwdriver.
Note I got the VW style Bosch dynamo as fitted to late s. Partnumber Then I checked the regulator. The regulator was not original, had no brand name on it, was black painted and looked identical to the original Bosch one.
It was only marked "made in USA". The field resistor was 8 ohms. This wire goes straight to the battery so make sure it doesn't touch anything while loose. If not replace it. It's not worth trying to adjust these regulators. Part number 0 The Bosch field resistor Renault 21 Savanna K48 1986-1994 Bosch S3 Battery 56Ah Electrical Replace Part only 2 ohms! The first time I drove with this new regulator it became Renault 21 Savanna K48 1986-1994 Bosch S3 Battery 56Ah Electrical Replace Part hot!
This was normal as we had to charge the battery from a low 12,5V. Charge current must have been high. BUT still she wouldn't start as should be.
At first try that is! The problem was found in a bad contact what else? It can make a difference. I fitted a wire straight from the fuse panel to the key switch Renault 21 Savanna K48 1986-1994 Bosch S3 Battery 56Ah Electrical Replace Part the grey connector. Your car is now fed by the power supply. An old PC power supply is just fine for. Don't use anything else but a 12V supply or you risk burning a few things!
These resistors are cheap and availeble at any electronic part shop. Solder a wire at each side of the resistor with a crocodile connector to ease installation.
Make one 5 meter long test wire. With another test wire BBosch to the -input on your voltmeter we now measure each point in the chain and can see the actual voltage loss they cause. The 5 meter wire makes it easy to go to any point around the car you wanna check. For the ignition circuit you will pass the fuse panel, ignition switch and grey connectors under the dash board. To find bad contacts, current must flow through it to create a 19861994 drop. No current, no voltage drop.
Just like water flowing through a tube. This method works better then measuring the actual resistance. I like the Fluke 10 series meters for this work. Not too expensive and more then accurate enough for this task. Renault 21 Savanna K48 1986-1994 Bosch S3 Battery 56Ah Electrical Replace Part seen too many bad contacts on crimped connectors! I cut off the plastic from the crimp connectors, then make Electrkcal soldering Renault 21 Savanna K48 1986-1994 Bosch S3 Battery 56Ah Electrical Replace Part put a heat shrink or rubber sleeve around it.
Frequently the solder will not flow nicely on the copper of the wire because it's oxidized. If the copper has a green coating on it then that's the oxidize. Its normal to have this when copper comes in contact with moisture but luckily Renxult doesn't affect the electrical conduction.
It only makes soldering difficult. To get rid of it cut off an inch or so and strip it, if your lucky you'll get back to nice clean copper. Mostly this Relpace the case. What else can we expect if we got the Pqrt sixties wiring in place. File off the oxidize to get rid of it. Seat Altea 5P1 2004-2016 Bosch S3 Battery 70Ah Electrical System Replace Part the ignition coil the connectors can fall Boschh as they hang upside-down.
To prevent this I use crimp Elecrtical with a push-in lock inside. Don't know their part number. The connectors for the reverse gear switch on the gearbox were another problem. The AMP ones are just too small in diameter to fit right.
These regulators were used on most of the English motorcycles in the fifties. The mechanical ignition points were replaced by a Petronix unit part number V. It works fine and is easily Battrey. Actually this is the set for a VW. I did this on the advice from the local dyno-man and he is good! Three of the first four cars arriving in a Belgian 24 hours race were tuned by. The resistive spark plug cables help to get a higher voltage which helps to prevent plug fouling.
The only problem with them are the spark plug connectors. I cut them off and replaced them with the bakelite Porsche style ones. While on ignition, check the timing marks Renault 21 Savanna K48 1986-1994 Bosch S3 Battery 56Ah Electrical Replace Part your pulley!
I had a pulley VW? I filed marks every 5 degrees to the right-hand side of the OT Electdical a degree rule. The clock still worked but ran too slow. They are adjustable from the backside. You must remove them to get to the adjustment screw but one advice: DON'T pull off the supply connector without supporting the white plastic cover! The Rwplace is fitted on three anti-vibration rubbers with E-type circlips. They can slip off if you pull too hard.
Then the circlip falls in the clock housing and can't Savanns removed without taking off the clock front panel. This front panel is "crimped " onto the clock body which makes is VERY hard to remove.
Something I don't wanna do yet as I'm afraid of destroying it. Instead I installed a quartz clock found at a Porsche autojumble. It looks identical except Renualt has quartz written on it. This clock is always on time. Being a technician I'd like to solve technical problems but my sure has given me more then enough things to think about Renault 21 Savanna K48 1986-1994 Bosch S3 Battery 56Ah Electrical Replace Part my experiences can save you ers some search time.
