My car is a Toyota Tercel 1987 DX Wagon. I wanted to connect a digital tachometer to measure the RPM of the engine. I connected the Battery terminals to the battery. I Connected the signal wire to the -ve end of the Starter coil (Coil Pack). Reading appears as 8888. Some times it shows 97,85, 100, 9...

We used to do it with safety precautions. In Sri Lanka, a new battery costs nearly one to half a months salary. Health risk is same when do change the acid. Old acid have ionic Lead. Should never pour them to area near to a cultivation or a water source. In most of the counties, battery service cent...

Mr. Petros, "Rapid charge and discharge" is the thing achieved by a trickle cell charger. In addition to that slow current also can do this as mentioned above. When plates are damaged, it is a simple way to repair it by cut open and replace plates. 1. Cut a rectangular area on the upper su...

Mr. Petros. PbSO4 deposited on the plates are the problem when over-discharged . In such instances, I use 2A charger or a Trickle cell charger for 24 hour charging. Slow current and pulsate current can break down Lead Sulfate. When do the charging, charging stops at a one level and no advance in the...

After cut and examine the cell, it could be noticed a heavy damage to the plates.

I accidentally charged the battery with closed caps. It could be the cause for such a damage to the 1 1/2 year old battery.

Replaced the cell with new plates and repaired.

Now battery works fine.

Thank you very much Mr.Petros for your valuable answer. Should I check the voltage difference after attempt to crank? Before attempt to crank (just after charged),there are 2.2V - 2.3V in-between good cells. There is 1.9V between the bad cell and the adjacent good cell. After attempt to crank, there...

My car is a Toyota Tercel 1987 DX Wagon. Car has a 65amp battery with 6 cells. When attempt to start, car only has the sound of the solenoid. Doesnt start. When I charge the batter, It charges upto 13.6 V. After attempt to crank, Battery voltage drops to 10.6V and that is kept steady. It dosnt comes...

My car is a Toyota Tercel 1987 DX Wagon.

I want to make a add a gauge 12 frame bar clip.

Suggested solutions are cut gauge 12 bar or Adding double layer of gaude 18/16 clip.

Which is most suitable one among them.

Thank you for your valuable advice.

My car is a Toyota Tercel 1987 DX Wagon. Body frame clips behind the left front wheel is damaged by some cause. It is made of gauge 18 sheet. What happens if I add a clip of gauge 12 (with more strength) like that is infront of the rear wheel which bears the lower arm? Main body frame is divided in ...

Again thank you Mr. Petros for your valuable advice.

No. Your advice had a critical point. Engine has a mild tickling sound. It is mentioned that tickling sound comes from either by valves or by contacts. Perhaps valves may have a problem.

Yes when RPM exceeds vibrating range drops to 18-16 range.

Problem is If the valve guides are worn, compression should be dropped. Isnt it?

My car is a Toyota Tercel 1987 DX Wagon with 3A engine. My car engine sound is smooth but not upto the expected level. So I tested the manifold vacuum. There is a rapid oscillation of the needle between 17 and 13 inhg. So I have done a compression test. All the cylinders had 150 psi (desired range w...

I have got made a Input shaft like thing with wood from a lathe worker.

I brought the clutch plate to him with the inner diameter measurement of the bearing. (Also a piece of wood)

I think it could have been better if made from iron.
