I'm new to the Honda forum trying to see if anyone can help with a little problem I have, theres no 12v going to my distributor so therefore no spark. Can anyone tell me where to even begin to check? Or what sends signal to the distributor?

 

Check ignition fuse (No 19, 50A) in underhood fuse box. If it were out a lot of other things would also be out.

More likely the ignition switch in the column has failed, preventing power to the blk/yel wire.

Replacement is fairly simply job. See DIY forum here and youtube videos for help. Only tricky part can be removal of security bolts using a punch or small sharp chisel. Usually bolts are not very tight so one small turn will free them to turn by fingers. I reused the same security bolts and reset them w/ chisel.

good luck

 

Thanks for the the quick response let me check and I will get back at you but considering a variety of mechanics have already worked on it and they replaced several parts there's no way of telling if that fuse was blown out or not all I know is the dizzy is brand new but I noticed no 12 volts, quick question if that fuse wasn't blown out at any time what else can cause this problem?

 

Only things between battery and distributor blk/yel feed wire are main system fuse (100A), fuse 19 (50A), and ignition switch. If fuse 19 is good, then ignition switch is about all that's possible besides a wiring or connector fault.

good luck

 

OK now the fuse #19 checked out OK so did the main fuse and ignition switch now thing is as I crank the car the ignition switch volts drop from a 12v to 8v would faulty grounds have anything to do with it?

 

Could be a ground issue but I'm with TX, the electrical part of the key switch - you can replace the electrical part and not the whole thing (key and tumbler) - has pitted contacts causing bad connections.

With the key to on - if the voltage to the BLK/WHT wire going to the dist is low (below battery voltage) or not there at all - sounds like a classic bad ign contact switch.

OK thank you for all the suggestions, now I got power going to the blk/yellow wire, thing is still no spark and all I did was replace the ign switch, any further suggestions?

 

Check from distributor ground to battery negative posts. Voltage drop should be small;< 0.2 volts (a guess since I don't know current load). If you're seeing 4V drop, it could be a ground fault. Check ground from distributor to thermostat housing.

good luck
