Rev Counter Only Works With Heaters On?

[MiniGibbo 142]

Hey youll have to bare with me im new with 205's only had my Rallye a few hours so far..

 

Basicully its a 93 Rallye with a S1 106 rallye engine and box, the original rallye dials are still fitted and work fine but only when the heaters are on other wise nothing.

 

Anyone got any ideas?

i saw this advertised on ebay looked like a nice motor could it be something simple like an earth that controlls the heater is also wired to the clocks?

Thanks im really pleased with the car, ill do a write up on it later.

 

As for this problem, i also asked on rallyereg and a couple of them also suggested an earth fault. Ill have to get my self a multi metre then i suppose lol..

I also noticed today when i indicate with the blowers off the rev counter "half" works..

Sounds like an earth to me.

Thanks guys my first point of call will be checking and cleaning all earth points i can find on the car lol.. is theyre any that are renowned for being problems?

 

Then i plan to solder every connection thats crimped in the car :S

I wouldn't personally solder them - I'd cut back to fresh wire and re-crimp with the proper crimping tool. It'll last much longer done that way!

[MiniGibbo 142]

Surely crimps stand more chance of pulling out than soldering them?

[Anthony 1,003]

Six of one half a dozen of the other.

 

Poorly crimped connectors are liable to pull out, but an inadequately supported loom with solder joints risks breaking (the solder makes the wire quite brittle)

 

Either method will be fine providing that you do a good job, and either will be a potential reliability headache if done poorly.

[jackherer 543]

A DIY style crimped joint is going to fall apart but a proper F crimp has two crimp points, one to the inner conductor and a second one around the insulation that holds it securely against fatigue and has the secondary benefit of sealing the cable from moisture to some degree. If you solder the crimp you lose the flexibility.

 

 

The biggest issue with 205 wiring isn't the connections though, its the condition of the wire inside, its normally too corroded to take solder properly and a new crimped joint (even a properly done one) will be unreliable. The only solution is to cut back to clean wire and replace as necessary.

started cleaning the bay today as it really started to bug me how everything is dirty, came across a load of earths that looked iffy..

 

going to give them a better look on the weekend.
