So it suppose to slide out pretty easy, right?

So yesterday I was trying to take it off to check on the stator coil. I removed the 3 bolts and tried to take it off. However, the bottom on the cover seemed to be really stuck. It felt like something was glued/ connected behind it. I didn't want to destroy it so I just bolted it back on. I am just wonder if I have to ply it out/ use more force to take it off.

So, I took my Seca 2 out for the 1st ride of the year after a long winter. It turns out that my battery is so dead it'll kill my bike if I don't my my rpm over 1500. I'm now in the market of a new battery and the book calls for YTX9-BS. However, the pervious owner put a YTZ12S MF in it. And now I'm thinking about maybe getting a YTZ14S. I am wondering if there is anything against this move. Thanks! Vincent

Hi guys, I posted this question on the workshop section but has yet get any reply. So I thought I might post a link here too.! Thanks! Click Here!

Well, don't know how many people read my post in the classic section but boil things down is that my oil press. light (yes I'm sure it's press. on this bike) is not working. Went through 3 different switch (nos & used) with no avail. Someone suggested it's the wiring. Do you guys think it's somewhere in the wire harness? If I want to replace the harness, what are the procedures? I have the factory service manual but it didn't say how to replace the harness (Yes I'm a noob). Anyone can give me some pointers? Thank a bunch!

I got mine from the local motorcycle store for about $30

When I unscrewed my old switch, there was oil coming out. Plus if I have a blockage on the passage and assume the switch is working properly, shouldn't I have the light on all the time?

Hi all, As I posted earlier my oil press. switch is not working. I took it out and tested it with an ohmmeter today and I got about 40 on the R x 1k scale. I'm not sure if it's normal or not. Since there's no pressure the contact should be connected (grounded), hance, the ohms should be close to 0 (current can go through, lite up the indicator) . Am I right?

the bulb is not the problem I'm pretty sure. And I don't think the wire is earthing out because if it does then the light should be on all the time. So somehow the switch is not connecting (normally when there is oil press.) even when there is no pressure at all, like when the bike is off. Does anyone knows how to test an oil pressure switch? Thanks!

The oil press. switch IS the gnd itself. Somehow when it's low of oil press. it should switch on. I don't know how all this works. BTW, the oil pressure switch is NOS from ebay.

I asked the same Q. on xjbikes forum and the people said the wire is probably broken. My question is if the wire is broken isn't it shouldn't send any signal to the lite at all no matter it's gnded or not?

Hi all, I got a XS400J 1982. My Oil Press. Lite is not working. Gnd the wire w/ a tester and the light will go on. Got a new switch in but the lite still won't work (unless I gnd it will a tester). I'm outta clue. Anyone think of anything? I don't seems to have press. problem tho.

That was what I did when I had headlight problem last time. 1 I got a car battery charger/jumper (self-contain unit, not the cable). 2 Find which pin is gnd and which is hi/low beam. 3 Connected the black cable to the gnd and the red to either one. (Watch for sparks). If it works then it's not the light problem and look somewhere else. Hope this help.

According to the book, I grounded the wire (behind the headlight at both side of the 6-pin connector) and the oil light will goes on. So I'm kinda think it's not the wiring. Anyhow, I have a sending unit coming in (Lucky to find one NOS) and my question now is: Where is that switch? Thanks all!

Correct. Seems like bad grounding on both. THe hi-beam is a low priority but I thinking the oil pressure switch is faulty. Now the question is where is that stinking switch...
