93 del sol si blowing #15 fuse under dash, when reverse Engaged.
Hi, I got a 1993 del sol si, and for some reason every time I put it in reverse it pops the #15 fuse. It is manual trans, but a few times it hasn't blown. When it blows I loose my tach, temp, and all, except fuel gauge. And also loose power windows and reverse lights... help please!!!

I'll also add, when I take out the blown fuse I can take my tester, set it to where it beeps when the leads are connected, ground one lead, and put the other in the fuse slot and it beeps telling me I have a short somewhere.... anybody else ever had this problem with this fuse and the same accessories going out?
Re: 93 del sol si blowing #15 fuse under dash, when reverse Engaged.
I forgot to mention, I have already inspected the bulbs and plugs in the rear, and also un-pluged the transmission wires and re tested and still have a short. But, when I tested the reverse bulb sockets with the bulbs removed, it tested good, not shorted.
Re: 93 del sol si blowing #15 fuse under dash, when reverse Engaged.
Yes, still blows. I'm thinking maybe a wire wore down bare somewhere, but not sure if somebody had the same problem before or not. I'll double check later after work and make sure it still blows with it all unpluged.

If fuse still blows with switch unplugged and transmission in reverse, the short is almost surely in the reverse switch itself.

Ok, I'm new to this site, and also new to owning a Honda, could you tell me where the reverse switch is? Or what it looks like on this? That way I can rule it out.

Set meter to read Ohms on lowest scale.
Touch one meter probe to power wire or pin you want to test and other to the (-) battery post or other ground source. A low Ohm reading would indicate continuity to body ground (=short to ground).

Ok, I checked it right quick before it rains, the first pic is from the "I believe" yellow wire, and the second is from the "I believe" green wire. It's kinda nasty and hard to tell the colors. The last pic i used my meter on this setting which it beeps when something is grounded completing the circuit between the meter wires, just like touching the ends together, which it doesn't beep at all on either wire.... if I can get these to upload....

I also pulled the plastic off from the drivers side door way down bottom and pulled the carpet back, from what I could see it all still looked good like new, without rubs. I will have to get more in depth with wire searches if it's not the reverse switch in the trans. Does anyone know if that reverse wire from the switch goes behind the engine between the intake manifold and the brace? I've heard of alot of wiring problems back there. I just replaced the engine, but it was not running when I got the car, so I'm not sure if it was a problem, or if I caused it.

If the fuse blows with the switch unplugged it can't be the switch, the green wire, or the reverse lights. You need to check for shorts in the yellow wire and other things that are attached to the same fuse. It seems just a conicidence shifting into reverse. Though when you go in reverse the engine tilts the other way slightly, that could be a problem if the engine harness is frayed.

Can I assume that this^ test was done with the reverse switch unplugged and on the wire harness connector rather than the switch connector? If so, the test removed the switch and the connector with its two associated wires from the circuit. By doing this, your test results showed that the short was also eliminated from the circuit, indicating that the short is in the switch itself or its downstream Grn/Blk wire. Replacing the switch will solve the problem.

Was the switch connector unplugged from the rest of the circuit in this^ test? If so, the test on the Yel and Grn/Blk wire would only be able to detect a short if the transmission were also shifted to reverse. Redo the test this way.
Also do the converse test by unplugging the switch and then testing for continuity to body ground on the Grn/Blk wire in the wire harness connector.

Yes, I only tested the switch unplugged, but didnt think of doing it with it in reverse. I will redo it. And will also check the other plug on the harness side. Dont know why I didnt think of doing it in reverse since that's when it blows. 🤔🤔🤦*♂️🤦*♂️🤦*♂️

Just thought of one more thing...., while I had it unpluged, I also checked the fuse slot and my tester beeped saying I had a complete connection "short"... before checking it I turned the key on and found out which side of the fuse was power, and done the test on the other side which should be going to the short.
