Old dash/New Dash (secondhand)...fuel gauge question

Hi all, how are things ....i got a newer second hand dash for my 906, looks like brand new compared to my old one.....my question is if anyone can answer it is....the old fuel gauge read the fuel all the time with no problems, no when i accelarate then slow down with the new one the fuel gauge goes to empty and the fuel light comes on until the fuel gauage reads normal when back to normal riding, the old one alsways gave an acurate reading at all time when accelating and stoping....fuel sender in the tank hasnt changed at all........??????

I know next to nothing about electrics, wazza, but maybe you can put something like a resistor into the system to 'tranquillize' the gauge. Finnpaso will probably be able to advise you more.

Hi Wassawiseman,

My fuel gauge has always operated like that. As the float in the tank moves up and down (especially when there is not much fuel in it) the needle on the fuel gauge faithfully records the motion. Don’t think of the gauge as operating incorrectly, think of it as being extremely accurate, as it shows all the fuel movement.

How you doin' Fraser?

The thing is, his previous gauge used to read ok with the same float and sending unit, which suggests to me that his new one might do so also with less current. Maybe yours too.

But, as I indicated, when it comes to electrics, I really don't know what I'm talking about.

Talk about understatement!! :neener:

Thank you, Jon.

What do you think about my resistor idea?

I tried one time to stabilize my 750 fuel meter with quite big electrolyte capacitor (beetween meter + and - poles), but it didnt help at all. 907 have much stable fuel meter and seems to me, that all modells have same sender unit (i havent check that from my microfitche) and 907IE have some way different meter (much more stable)... I dont know about 906. Skins have made some job to adjust meter to be more accurate. I havent done that, but propably that can be done by adjusting float arm.... Anyway, i think, that 750 Pasos fuel meter is "onekind Italian character", so not so big problem, if know, how it normally function.... :laugh:

Hi Wassawiseman,

I see that you are an active participant on Trademe. Have a look at this: http://www.trademe.co.nz/Trade-Me-Motor ... 063091.htm
We are bidding on the same item. I don't need it, it was just an opportunity to aquire another spare part. Do you need it, or just fancy another as a spare?

Fraser.

Hi Fraser, yeap im bidding on it.. as paso parts are getting harder to find...mind you i think Phil will have a high reserve on it??....my tank leaks a bit here and there so hoping to get another tank that dosnt leak, and get it resprayed, mind you i wont go above $150 i guess......do you collect spare parts as well?

Yep, you need to be a horder, as you never know when that useful little item will one day be required.

I don't know enough about elec-trickery to say. I disreagrd the gauge and go by mileage fo fill up.

I think, somewhere is older topic to this thread about fuel gauge...

I put the old fuel gauge into the newer dash and it works absoulity fine as it did before, pushed the bike up n down on the front brakes and it hardly moved, draned the fuel, and it read correctly, the old one drove me crazy....willl make the best i can out of both and keep as spare parts ( just in case)........so im not sure what the other one read the way it did, but problem is now solved....thanks for all the input folks....

Austin Rover cars had their gauges "settled" by the use of a "ballast resisitor" a little three terminal gizmo which you should still be able to get from Lucas and or a Leyland dealer. It basically slowed down the electrical pulses so that the tank unit swishing about wasn't reflected on the gauge reading. It's smething I intend looking at (along with repacing the clock with the insides of a Fiat Panda one) sometime soon
