91 crx si with battery light flashing

I have a 1991 Crx Si with a B16A1 DOHC VTEC motor and the battery light has stayed on when i bought the car from my friend. Recently the battery light flashes so i sanded down all the ground wires and tightened the connections. The light stopped flashing for about 3 weeks and now its doing it again. I also have a Apexi VTEC controller that says my battery's voltage ranges from 13.2 - 14 depending on if i have the wipers on and etc and at night when the light flashes it makes my headlights flash and that gets annoying. I dont know what to check anymore and the car starts up fine, the light doesnt flash until the car is warmed up though. If any one can help i would appreciate it. Thank You!

    I did and everything tested fine. now when i start the car the battery voltage is reading 14.9 and my friend thinks its the regulator inside the alternator because after a while his voltage kept rising until he eventually started smelling something burning and the alternator eventually overheated and started melting so maybe ill get another alternator soon. but thanks for responding back. if you have any other suggestions please let me know.

SOURCE: I HAVE A 1991 CRX

Yes the starter from the SOHC motor will work on the DOHC. I have done it many times myself when I had my CRX back in the day. I also had the same question when I first changed mine.

What is the firing order for a 1991 crx si

the firing order for your 91 crx should be 1, 3, 4 and 2. You need to identify where the rotor points to when cylinder 1 is at top dead center.
Cylinder number 1 is the one closest to the accessory belts (alternator, power steering , etc, hope this helps.

What is the firing order for a 1991 crx si

All Honda 4 cylinder engines that I have worked on have a firing order of 1342. That is the firing order on your CRX. #1 is the cylinder closest to the timing belt.

Valve lash 91 honda crx si 1.6 sohc

For this engine the valve lash if; Intake .007-.009 and the exhaust valves are .009-.011. Be sure to adjust these when the engine is cold, as a warm exgine will affect the measurements. The locknuts should be torqued to 10 ft/lbs. REMEMBER..."loose is good"..in other words when adjusting the valves DO NOT make them "tight feeling" with the feeler gauge. If you do, you run the very real danger of burning the valves. Honda, I believe, recommends that you should check these every 15k to 24k miles. Happy motoring !

I have a 90 crx si with a b16a vetec engine in it. I was wondering what kind of engine is in it because it is a swap. the motor number is 1207276? and i have an idleing problem and im pretty sure that its...

A B16A with no number fallowing it is a JDM engine. If it was a B16A1 for example it is a USDM engine. As for the idle problem its probably a tps sensor and if it idles really low rpms you should up the idle at the trottle body to idle at 800 rpms to be safe, To low of a idle will cause bearings to go out and throw a rod.
Lookj at the valve cover if it is a jdm you will know if it is a SIR or a SIR2, SIR has larger font for the DOHC and smaller font for the VTech The sir2 has larger font Vtech and smaller font DOHC. The SIR2 also has oil jets underside of pistons and rods to help lubricate piston rod conections.

Wont rev over 3000 rpms in any gear

Try disconect the battery from the car. Wait a minute and reconnect. This should reset the computer. This happened
to my moms Honda FR-V. The mechanic had seen it before.
Its worth a try.
