Huqvarna T536li xp repair

[Alinicoll]

Does anybody have any information, experience or places to refer to trouble shooting and repairing battery saws?

 

We have a couple of saws, one stopped working completely, the other runs intermitently.

 

Thanks

With the battery kit, you have two options, one is to strip, check and inspect and hope you get to the issue.

The other is to plug it in to the Husqvarna CST system and hope that gives you an indication as to what is wrong.

As Spud says, split the machine and check all the connections, pay special attention to the battery connection area ( dirt and debris build up ), check the motor is free and no large build up of sawdust jamming it, when you say it’s stopped working completely what is showing on the control pad, any green lights? any red triangle. I have never had to replace a motor, so what’s left is a control board, a control panel, a micro switch actuated by the chai brake some wiring and a switch, so assuming all connections are secure and clean, you can hear the micro switch click when you actuate and load the brake, I would think the control board has a fault.

Thanks for the replies, 

 

The one that is stopped completely has no lights come on and makes no sounds or movement. I'll check the connections again and see if that helps.

 

The one that runs intermitently switches on and the motor runs, but under load it looses power and then regains it intermitently.

 

I'll have another play with them when I get the opportunity.

Battery kit out of warranty= generally beyond economical repair. More landfill

 

Petrol kit out of warranty= repairable at reasonable cost. Extended life. Less landfill

I still don't fully understand why that has to be the case apart from a lack  of expertise in fixing them or  by manufacturers, (possibly by poor design) making the spares & maintenace uneconimical  compared with parts for petrol ones.

 

Think part of the  problem is  a  faster  obsolescence as each new gen comes out.  I like makita as the 18v  platform has being arounds for ages and a big % of total the cost is in the batteries.

 

Have read that electric cars will need less ongoing service work than ICE ones as  less to go wrong so garages will lose out.

 

Quote

Independent auto shops — of which there are more than 160,000 in the United States — have always relied on minor repairs, such as oil changes and new tires, to get customers in the front door. To many a car owner’s surprise, one minor repair often leads to a series of others, giving auto shops a chance to make more money and establish a rapport with customers that can serve them for years.

 

Electric vehicles threaten to upend this income stream.

 

Unlike gasoline cars, electric vehicles require no traditional oil changes, fuel filters, spark plug replacements or emission checks. In most cases, you can wave goodbye to changing timing belts, differential fluid and transmission fluid. EV brake pad replacements are less frequent because regenerative braking returns energy to the battery, significantly reducing wear on mechanical brakes because they’re used less to slow the vehicle.

Analysts estimate that the repair bills for EVs would be lower and less frequent than the tabs of their gas-guzzling counterparts.

The Chevy Bolt’s maintenance schedule requires owners to rotate tires every 7,500 miles, replace the cabin air filter every 22,500 miles and have the coolant flushed every 150,000, according to Chevrolet. “And . . . yeah, that’s it,” as one writer recently mused. Some of those parts can be purchased online for less than $20.

 

So they are  kind of claiming the opposite for electric cars - cheaper and more  easy to fix, but maybe that will be less true in reality....

 

Im not sure if they are also designed to not last as long ICE ones and be scrapped/replaced faster?

 

 

 

Being green would be keeping & retro fitting upgrading older cars for as long as possible. (Bit like Cuba)

There really are only 5 major things that can and do go wrong-  battery, charger, switching, PCB and motor. Labour rate to repair is the same as a petrol. Generally electric stuff is more labour intenstive to diagnose and repair as they are a fiddly clamshell construction, and predominantly just by looking you can't actually 'hear' or 'see' the issue unlike petrol, so testing is required. When you quote an hours labour to get into it and then diagnose the issue even before a repair this can be over £50- however, providing the operator still has the good battery and charger, then for them a body only replacement machine makes more economical sense to purchase rather than repair the old 'body' At that point then we are often asked to 'recycle' (or dump) the faulty unit

 

This 'green' machinery lark is a con

Thanks good explaination understand it better now.

 

Is the automatic electronic fault diagnose software not  that reliable?

 

 

 

[pleasant]

Can be.....if you take the plunge and shell out for all of it. But if you are an agent for half a dozen manufacturers and all testing equipment is brand specific it's can be very expensive. Taking into account the cost of diagnostic equipment and labour, even if you can tell a customer what's wrong because you have the 'kit' if it's beyond an econmomical repair, then you still aren't earning anything from the repair that never materialised. Yes, we get paid for doing the diagnostics to provide the customer an estimate oif costs, but we have to keep this charge lower that we would like to, because even the charge for an estimate can and will put people off even considering a potential repair

So, a possible option if I suspect a particulat part is faulty would be to just swap parts about from different saw!

 

Which to be honestf is often how petrol saws get fixed 😂
