Delphi 5 question

[benadeja]

Hi ,

 

I have a question regarding the Delphi 5 , as soon as I go downhill and go over the speed of say 40 km/h , then it is as if the unit loses the signal and shows my current speed to be between 14 and 18 km/h , anyone else experience this , as soon as my speed drops to below 40 km/h again then it shows the correct speed , could it be that my magnet is maybe moving around/virbrating at high-speeds not sure what could cause this ?

 

Any ideas ?

 

Thanks.

I had a similar problem in December riding down a mutha of a hill (after climbing it - 4 km at 14%).

 

Coming down at around 70 km/h I had no reading on my Delphi. My friend who was following me told me the speed later. I think I know what it is, but have not had the chance to get that sort of speed up again.

 

Your speed sensor probably faces toward the front of your fork. This will, if the cable ties are not tight enough, cause the transmitter unit to move away from the magnet. If you have a 3 mm gap, it only has to move another 2 or 3 mm for "contact" to be broken.

 

I moved mine around to the back of the front fork and so far so good. I have not ridden that fast again (my valley is not really a valley, more like a hollow).

 

I hope this helps.

Thanks so much will try that yes my speed sensor is actually on the front so will move it to the back when I get my bike back , could be that the magnet also moved cause I had to put the magnet skew on my spoke as the magnet is too wide to put it straight facing the speed sensor if it faces the speed sensor it hits my fork so had to install it with a bit of an angle on the spoke ... had an accident this weekend and it made me so cross cause it wasn't even my fault and I've been training so hard for the Emporers , and yeah sitting with a damaged rim and a cracked elbow so probably won't be riding this weekend
